President Donald Trump’s new national security strategy is set to be released on Monday.

A copy of the document obtained by The Daily Caller reveals a stark contrast between President Trump’s America First National Security Strategy and former President Barack Obama’s most recent national security strategy in 2015.

Renewed Focus On Islamist Terrorism

Trump’s new national security strategy places an emphasis on stopping Islamist terrorism and calls it out by name. Obama’s 2015 national security strategy referred to Islam just twice: once because it’s part of ISIS’ name and once to say the administration rejected “the lie that America and its allies are at war with Islam.”

The new national security strategy explicitly links Islamist ideology to jihadist terrorism.

“The United States continues to wage a long war against jihadist terrorist groups such as ISIS and Al Qaeda. These groups are linked by a common radical Islamist ideology that encourages violence against the United States and our partners and produces misery for those under their control,” the new strategy states.

Trump’s strategy also notes, “jihadist terrorists such as ISIS and al-Qaida continue to spread a barbaric ideology that calls for the violent destruction of governments and innocents they consider to be apostates. These Islamist terrorists attempt to force those under their influence to submit to Sharia law.” A source familiar with the strategy’s drafting process described the reference to Sharia law as a “huge” inclusion by the Trump administration.

Dumping Climate Change As A ‘National Security Threat’

Obama’s 2015 national security strategy prioritized climate change as a national security threat. Obama’s strategy devoted more space to the threat posed by climate change than to the threat posed by North Korea. “Climate change is an urgent and growing threat to our national security, contributing to increased natural disasters, refugee flows, and conflicts over basic resources like food and water,” Obama’s national security strategy said.

Trump’s national security strategy reverses that approach and does not identify climate change as a national security threat. In fact, it goes one step further.

“U.S. leadership is indispensable to countering an antigrowth energy agenda that is detrimental to U.S. economic and energy security interests,” the new strategy states. “Given future global energy demand, much of the developing world will require fossil fuels, as well as other forms of energy, to power their economies and lift their people out of poverty.”

The 2015 strategy noted that the administration was “working toward an ambitious new global climate change agreement,” which became the Paris Climate Accords.

Trump withdrew the United States from the climate deal last summer, denouncing it as a threat to American sovereignty.

In what appears to be a reference to the Paris deal, Trump’s new strategy states that “it should be clear that the United States will not cede sovereignty to those that claim authority over American citizens and are in conflict with our constitutional framework.”

Iran — Not Israel — Is The Threat To Peace In The Middle East

In perhaps the sharpest contrast to Obama’s national security strategy, Trump’s new strategy takes a hardline stance on Iran, which it describes as “the world’s most significant state sponsor of terrorism.” Obama’s strategy emphasized the need to protect the Iran nuclear deal — a pillar of his legacy as president.

Trump’s strategy notes that Iran “has taken advantage of instability to expand its influence through partners and proxies, weapon proliferation, and funding. It continues to develop more capable ballistic missiles, intelligence capabilities, and it undertakes malicious cyber activities.”

Trump’s strategy states that — despite Obama officials’ claims to the contrary — the Iran nuclear deal has done nothing to stop any of the above activities.

“These activities have continued unabated since the 2015 nuclear deal,” the document states. “Iran continues to perpetuate the cycle of violence in the region, causing grievous harm to civilian populations. Rival states are filling vacuums created by state collapse and prolonged regional conflict.”

Trump’s national security strategy explicitly blames Iran, rather than Israel, for conflicts in the Middle East.

“For generations the conflict between Israel and the Palestinians has been understood as the prime irritant preventing peace and prosperity in the region,” the strategy states.

“Today, the threats from radical jihadist terrorist organizations and the threat from Iran are creating the realization that Israel is not the cause of the region’s problems. States have increasingly found common interests with Israel in confronting common threats.”

The strategy notes that the U.S. will work “with allies and partners to deter and disrupt other foreign terrorist groups that threaten the homeland—including Iranian-backed groups such as Lebanese Hizballah.”

The Obama administration, in contrast, torpedoed a DEA operation against Hezbollah for money laundering and narcotics trafficking in order to preserve the Iran nuclear deal, according to a bombshell report in Politico Sunday night. The report said that the Obama administration’s reluctance to confront Hezbollah allowed the group to grow rapidly in size and expand its influence across Lebanon in particular and the Middle East as a whole.

Immigration: Ending Chain Migration, Increasing Vetting, Tougher Border Security

Obama’s 2015 national security strategy placed an emphasis on giving amnesty to illegal immigrants by giving them a “pathway to citizenship,” while paying lip service to the need for border security. The 2015 strategy framed the flood of illegal immigrants to the US-Mexico border as a “major consequence of weak institutions and violence” and emphasized the need for America to help those countries.

“American leadership, in partnership with these countries and with the support of their neighbors, remains essential to arresting the slide backwards and to creating steady improvements in economic growth and democratic governance,” the Obama strategy stated.

Trump’s strategy frames the immigration issue in terms of sovereignty, saying the U.S. “affirms its sovereign right to determine who should enter our country and under what circumstances.”

The document emphasizes the importance of knowing and controlling who enters the country through tactics like increased vetting, ending chain-migration, ending the Diversity Visa Lottery program and increasing border security.

“The United States affirms its sovereign right to determine who should enter our country and under what circumstances. The United States understands the contributions immigrants have made to our Nation throughout its history. Illegal immigration, however, burdens the economy, hurts American workers, presents public safety risks, and enriches smugglers and other criminals,” the Trump strategy states.

The document continues:

The United States will continue to welcome lawful immigrants who do not pose a security threat and whose entry is consistent with the national interest, while at the same time enhancing the screening and vetting of travelers, closing dangerous loopholes, revising outdated laws, and eliminating easily exploited vulnerabilities. We will also reform our current immigration system, which, contrary to our national interest and national security, allows for randomized entry and extended-family chain migration. Residency and citizenship determinations should be based on individuals’ merit and their ability to positively contribute to U.S. society, rather than chance or extended family connections.

Two recent terrorist attacks, the October truck attack in New York City and last week’s attempted bombing, were committed by individuals who entered the country through either chain migration or the Diversity Visa Lottery program.
