On August 9, an airplane belonging to the Saudi-led coalition appears to have hit a school bus in Yemen, killing 40 boys between the ages of six and eleven. According to investigators, the bomb was American-made—not a surprise, as the U.S. has been supporting Saudi Arabia and its allies in their efforts to drive the Iran-backed Houthi rebels and al-Qaeda from Yemen. The civilian deaths again brought to the fore concerns about Washington’s role in this bloody civil war, which has dragged on for almost four years and precipitated a humanitarian crisis. Noah Rothman comments:

Elsewhere in Yemen, another American bomb is making headlines of a different sort. On Tuesday, American and Yemeni officials revealed that they have high confidence that a U.S. drone strike killed Ibrahim al-Asiri, who was described by Barack Obama’s former acting CIA director Michael Morell as “probably the most sophisticated bomb maker on the planet.” . . . Asiri is one of many al-Qaeda leaders and mid-level commanders dispatched by U.S. drone patrols in Yemen, and Americans are safer because of those operations. Those American bombs get less attention than the munitions the United States provides to Saudi Arabia and its allies around the world, but they are all part of the same campaign.

The bomb that killed 40 young boys on August 9 was part of a shipment to Saudi Arabia that was approved by the State Department in 2015, under President Barack Obama. That was not a particularly controversial move at the time. . . . The possible disruption of America’s anti-terror operations [against al-Qaeda] in this theater wasn’t the only peril posed by this new conflict.

After taking [the capital city of] Sana’a, the Houthis descended on the strategic port of Aden, which is situated on the vital Bab al-Mandab Strait. That tiny, two-mile-wide northbound shipping lane leads directly into the Suez Canal and provides every port on the Indian Ocean with access to the Mediterranean and Europe. If the Houthis captured it, Iran would be free to shut the strait by deploying mines or harassing shipping vessels. No American administration, Republican or Democratic, would tolerate such a threat to international trade and global security.

[T]he alternative to a Saudi-led war is not American disengagement. . . . If American guided munitions were called onto targets by American observers on the ground in Yemen, it’s entirely possible that the kind of needless death that occurred on August 9 might have been avoided. But who thinks that direct U.S. intervention would mollify anyone condemning U.S. support for Saudi-led operations? Calling for immediate American disengagement, as so many liberal and libertarian lawmakers have done, is not a serious approach. It is a luxury available only to those who are not responsible for the preservation of the U.S.-led global order.

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.
