On Wednesday, the House of Representatives advanced a resolution to end American support for the Saudi-led war against the Iran-backed Houthi rebels in Yemen. A similar resolution is making its way through the Senate. To Evelyn Gordon, this effort is wrongheaded on both strategic and moral grounds:

On the strategic side, let’s start with the fact that [the Houthis,] an organization whose official slogan is “God is Great, Death to America, Death to Israel, Curse the Jews, Victory to Islam” isn’t one Americans should want ruling anything, much less a country whose location enables it to dominate a strategic waterway vital to the global oil industry. And without the Saudi-led coalition, the Houthis would long since have taken over Yemen. In other countries, like Syria and Lebanon, Iranian military and financial aid has repeatedly enabled its proxies to overwhelm the opposition; that this hasn’t yet happened in Yemen is only because there, unlike in Syria and Lebanon, the Saudi coalition has provided its local allies with substantial assistance, including airstrikes.

Second, empowering allies is always better than empowering enemies. Granted, Saudi Arabia is a highly imperfect ally, but it is at least nominally in America’s camp. Iran, by contrast, has been America’s avowed enemy since 1979, and its proxies have been responsible for hundreds, if not thousands, of American deaths in Lebanon and Iraq. . . .

Still, how can America possibly support a coalition that’s committing gross human-rights violations in Yemen? The answer is easy: horrible as Riyadh’s behavior is, the Houthis are worse. Thus, by ending support for the Saudi coalition, America would empower an even greater evil.

A perfect example is the issue of child soldiers. The New York Times ran a front-page story last month accusing the Saudis of using Sudanese child soldiers in Yemen. Though it didn’t provide many hard numbers, it implied that there could well be several thousand such soldiers. This is incontrovertibly bad. But what the Times carefully concealed from its readers is that the Saudis’ use of child soldiers pales in comparison to the Houthis’. . . . The Houthis openly admit to employing a whopping 18,000 child soldiers. Moreover, while the Saudis are taking boys aged fourteen to seventeen, the Houthis are using children as young as ten. And while the Saudis are recruiting their impoverished volunteers, . . . the Houthis . . . kidnap children outright. . . . [N]ational policy-makers’ job is to gather accurate information and then, if there are no good options, choose the lesser evil. In Yemen, the lesser evil is clearly backing the Saudi coalition.

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.
