Donald Trump leveled a national-security flamethrower at Hillary Clinton on Tuesday, blaming her for embracing an immigration policy that would drive more Islamic radicals to stage terror attacks like the one from which Orlando, Florida is only beginning to recover.

Clinton, he said, would negligently implement a 'catastrophic immigration plan' that would 'bring vastly more radical Islamic immigrants into this country, threatening not only our society but our entire way of life.'

'Ignorance is not bliss,' he said in a half-hour speech at Saint Anselm College in Manchester, New Hampshire.

'It's deadly. Totally deadly.'

CLOBBERING CLINTON: Donald Trump delivered a biting speech Tuesday on terrorism and national security, aimed largely at Hillary Clinton, following a deadly Islamist terror attack on a gay nightclub in Orlando, Florida

DUELING SPEECHES: Clinton and Trump split on gun control but agreed on the notion that radical Islamists are a threat to the LGBT community

Trump castigated the former secretary of state for comments she made in November 2015 during a speech to the Council on Foreign Relations.

'Let's be clear: Islam is not our adversary,' Clinton said then. 'Muslims are peaceful and tolerant people and have nothing whatsoever to do with terrorism.'

'That is Hillary Clinton,' Trump said, hammering her for her response to the weekend's bloodbath at a gay nightclub where more than four dozen people list their lives to a man who pledged allegiance to the ISIS terror army.

'The days of deadly ignorance will end, and they will end soon' if he is elected president, Trump pledged.

Clinton's response on Monday was equal parts gun control and a motherly embrace of America's gays and lesbians.

'She says the solution is to ban guns. They tried that in France,' Trump poked, referring to last year's terror attacks in Paris. 'One hundred thirty people were brutally murdered by Islamic terrorists in cold blood,' he said.

'Her plan is to disarm law-abiding Americans, abolish the Second Amendment and leave only terrorists ... with guns.'

'She wants to take away Americans' guns and then admit the very people who want to slaughter us,' Trump boomed, reading from a teleprompter. He pledged to meet with the National Rifle Association, the powerful lobby that has endorsed him, to 'discuss how to make sure Americans have the means to protect themselves in this age of terror.'

'CAN'T HAVE IT BOTH WAYS: 'Hillary Clinton can never pretend to be a friend of the gay community,' Trump said in New Hampshire, while she supports immigration policies that admit anti-gay jihadi immigrants

Trump effectively blunted Clinton's approach on anti-gay discrimination by joining her, however, saying that 'our nation stands together in solidarity with the members of Orlando's LGBT community' against a terrorist who plotted 'to execute gay and lesbian Americans.'

He called the carnage 'an assault on the ability of free people to live their lives, love who they want, and express their identity.'

That rhetoric would have sounded at home during the Democratic primary season, or on the stage of Sunday night's Tony Awards.

Trump, in fact, claimed that he would be a better and more effective advocate than Clinton for gay, lesbian, bisexual and transgender Americans.

'Hillary Clinton can never pretend to be a friend of the gay community,' he said, while supporting immigration policies that bring along with them the threat of more jihadi immigrants.

'She can't have it both ways,' he said. 'She can't claim to be supportive of these communities while [increasing] the number of people who want to oppress these communities.'

He emphasized that as president he would prioritize the protection of law-abiding 'people who are potential victims of crimes based on backgrounds or sexual orientation.'

Trump has been the Republican Party's most consistent immigration hawk during the primary season, advocating for tighter border control and catching flak along the way.

'We want to remain a free and open society ... [but] we have to control our borders. And we have to control them now. Not later. Right now,' he said Monday.

With dozens dead in Orlando, he said, 'we cannot afford to talk around issues anymore. We have to address these issues head-on.'

In a tweak to his previous proposal for a ban on non-citizen Muslims coming into the United States, he said he would use existing presidential powers to 'suspend immigration from areas of the world where there is a proven history of terrorism against the United States, Europe, or our allies.'

And doubling down on identity groups that cleave to Clinton's side, he emphasized that 'radical Islam is anti-woman, anti-gay and anti-American.'

'I refuse to allow America to become a place where gay people, Christian people, Jewish people are targets of persecution and intimidation by radical Islamic preachers of hate and violence.'

'This is not just a national security issue. It's a quality of life issue.'

Clinton delivered a speech Monday in Ohio that relied more on compassion and national introspection than on get-tough saber rattling.

Instead of vowing a get-tough policy on ISIS or al-Qaeda, she pledged to work overtime as president to root out so-called 'lone wolf' jihadis – the hardest terrorists to find because of their lack of links to organized movements.

Like President Barack Obama in the late morning hours, Clinton framed the Orlando attack as the result of anti-gay prejudice and an American gun culture that needs tightening.

She declared that the federal government needs 'more resources for this fight' and insisted that 'weapons of war' like the semi-automatic rifle used in the Orlando killings should be purged from America's streets.

And she complained that the U.S. government has done precious little to connect gun licensing with terror watch lists and other tools Washington uses to manage threat levels.

'If the FBI is watching you for suspected terrorist links, you shouldn’t be able to just go buy a gun,' she said.

The U.S. Constitution, however, guarantees citizens the right 'to keep and bear arms.'

While state and federal agencies can curtail those rights in cases where Americans have been convicted of crimes, gun-rights and civil-liberties groups have consistently pushed back against attempts to extend that power to mere suspects.

Clinton's most telling jab at Trump, a line one campaign source said was kept in her speech from an earlier draft before the Orlando shooting, was a dig at the billionaire's penchant for self-promotion.

America, she said, is 'not a land of winners and losers' – 'a country of "we," not "me".'

She also sought to drive a wedge between Trump and moderate Republicans, praising former President George W. Bush for communicating 'a message of unity and solidarity' to Muslims after the 9/11 terror attacks in 2001 – the opposition of Trump's focus on Islam as an incubator of terror-minded threat groups.
