Liberals on Twitter are taking aim at President Trump for leaving a flippant note while visiting Yad Vashem, the Holocaust memorial museum in Jerusalem, Israel, and contrasting it against the lengthier note left by his predecessor, Barack Obama.

Trump, Obama notes left at Yad Vashem, Israel's memorial for the Holocaust.

Now, I'm no defender of Trump and have long been critical of him for his narcissism and lack of seriousness, but I'm much less concerned about what he writes in a note, and more interested in what he will do as president to ensure the words "Never Again" are more than empty rhetoric.

In Obama's case, he was comfortable using high-minded rhetoric when discussing the Holocaust, but as president, he made the world a much more dangerous place for living Jews.

Obama, during his time in office, had a hostile attitude toward Israel, which is home to more than 6 million Jews — and consistently portrayed Jewish housing construction as the biggest threat to peace in the Middle East. Meanwhile, he cozied up to Iran, giving it $150 billion in sanctions relief to help it finance terrorism, allowing it to build ballistic missiles, increasing its conventional power, and putting it on a glide path to a nuclear weapon — even as the nation's leaders threatened to destroy Israel. In selling his deal, he employed historical anti-Semitic stereotypes that in effect portrayed wealthy Jewish donors as exerting a disproportionate and nefarious influence on U.S. lawmakers, who couldn't possibly oppose his deal on the merits. And in his outgoing act, he allowed the United Nations to pass an appalling resolution condemning Israel that described Jewish holy sites as being on illegally occupied territory.

If people want to attack Trump, there is plenty of ammo. But words are empty. In Obama's case, he spoke solemnly about dead Jews while he imperiled those who are living.
