According to available estimates, over 500 people have been killed by Bashar al-Assad and his allies in the bombardment of Eastern Ghouta, an area close to Damascus. Besides artillery and barrel bombs, Syrian forces have also been using chlorine gas on the civilian population there. The editors of Bloomberg urge the U.S., and its Western allies, to take a stand:

The moral responsibility for Eastern Ghouta clearly belongs to the Syrian government and its primary sponsors, Iran and Russia. But the West has hardly covered itself in glory with its efforts to stop the atrocities.

First, it failed to get any serious sanctions against Syria at the United Nations Security Council. And then, of course, there was President Barack Obama’s infamous “red line” warning that the U.S. would respond militarily if Assad used chemical weapons on his people. The dictator called Obama’s bluff, one of the worst humiliations for U.S. foreign policy in the post-cold-war era. . . .

But the West hasn’t been [entirely] spineless. Last April, after a sarin-gas assault, President Donald Trump authorized a large-scale cruise-missile attack on a Syrian air base. At the time, many scoffed that this was a token effort that did relatively little harm to Syria’s military. But there has been no verified use of sarin in Syria since the U.S. struck back.

It’s time for another red line, one that the U.S. won’t back away from. Trump should tell Assad and his Russian backers that any more proved use of any chemical weapon, including chlorine, will be met with even greater retaliation than what happened in April. It certainly won’t end the fighting in Eastern Ghouta or across the country, but it may take away one of Assad’s most unconscionable methods of terrifying his citizens.

Two extraordinary events demonstrate something important about Israel’s most fervent adversaries. One was a speech given at something called The People’s Forum (funded generously by Goldman Sachs), which stated, “When the state of Israel is finally destroyed and erased from history, that will be the single most important blow we can give to destroying capitalism and imperialism.”

The suggestion that this tiny state is the linchpin of a global, centuries-old phenomenon like capitalism goes well beyond anything resembling rational criticism. Even if Israel were guilty of genocide, apartheid, and oppression—which of course it is not—it would not follow that its destruction would help end capitalism or imperialism.

The other was an anti-Israel protest that took place in front of New York City’s Memorial Sloan Kettering Cancer Center, deemed “complicit” in Israel’s evils. At organizers’ urging, participants shouted their slogans at kids in the cancer ward, who were watching from the windows. Given Hamas’s indifference toward the lives of Gazan children, such callousness toward non-Palestinian children from Hamas’s Western allies shouldn’t be surprising. The protest—like the abovementioned speech—deliberately conveyed the message that Israel is the ultimate evil and its destruction the ultimate good, cancer patients be damned.

The fact that Israel’s adversaries are almost comically perverse does not mean that they can be dismissed. If its allies fail to understand the obsessive and irrational hatred that it faces, they cannot effectively help it defend itself.
