In the upcoming summit between the Russian and American presidents in Helsinki, the future of Syria is likely to rank high on the agenda. Russia’s foreign minister, Sergei Lavrov, has already made clear that Moscow won’t demand a complete Iranian withdrawal from the country. Donald Trump, by contrast, has expressed his desire for a complete U.S. withdrawal. Examining Moscow’s track record when it comes to maintaining its past commitments regarding Syria, Eli Lake urges caution:

Secretary of State John Kerry spent his last year in office following Lavrov all over the world in an attempt to create a U.S.-Russian framework for resolving the Syrian civil war. He failed. . . . President Trump [now] wants to get to know Putin better—and gauge his willingness to help isolate Iran. This is a pointless and dangerous gambit. First, by announcing his intention to pull U.S. forces out of the country “very soon,” Trump has already given away much of his leverage within Syria.

Ideally, Trump would want to establish a phased plan with Putin, where the U.S. would make some withdrawals following Iranian withdrawals from Syria. But Trump has already made it clear that prior [stated] U.S. objectives for Syria, such as the removal of the dictator Bashar al-Assad, are no longer U.S. objectives. The U.S. has also declined to make commitments to give money for Syrian reconstruction.

Without any leverage, Trump will have to rely even more on Putin’s word, which is worthless. Putin to this day denies any Russian government role in interfering in the 2016 U.S. election. Just last month, Putin went on Austrian television and lied about his government’s role in shooting down a Malaysian airliner over Ukraine. Why would anyone trust Putin to keep his word to help remove Iran and its proxies from Syria?

And this gets to the most dangerous possible outcome of the upcoming summit. The one thing that Kerry never did was to attempt to trade concessions on Syria for concessions on Crimea, the Ukrainian territory that Russia invaded and annexed in 2014. There was a good reason for this: even if one argues that the future of Ukraine is not a high priority for the U.S., it’s a disastrous precedent to allow one nation to change the boundaries of another through force, and particularly of one that signed an agreement with the U.S., UK, and Russia to preserve its territorial integrity in exchange for relinquishing its cold-war-era nuclear weapons.

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.
