Another criterion the commission laid out was “right intention.” An intervention’s “primary purpose,” it argued, “must be to halt or avert human suffering.” On this score, too, Trump’s proposed attack manifestly fails. Yes, Trump has spoken angrily about the children Assad’s chemical weapons strikes have killed. But it’s harder to take Trump’s claims of humanitarian motivation seriously when he has essentially shut America’s borders to Syrians: By this time last year the United States had resettled almost 6,000 Syrian refugees; so far this year the number is 44.

When it comes to John Bolton, Trump’s new national-security adviser, we don’t even have to guess about motivations. He’s said explicitly that averting human suffering is no reason to go to war. In 2008 he wrote an entire column entitled“The Case against Humanitarian Intervention.” In a 2012 article in National Review, he argued that, “the chimerical ‘responsibility to protect’ doctrine under which Obama justified U.S. intervention [in Libya] is not tethered either to reality or to American interests. To extend ‘responsibility to protect’ to Syria without contemplating the larger consequences for our interests worldwide would simply be irresponsible.”

Bolton has been clear: What Assad does to his own people is not a major American concern. That’s why Bolton opposed Obama’s call (which Obama later withdrew) for striking Assad after he used chemical weapons in 2013. America’s real interest in Syria, according to Bolton, in addition to destroying isis, is to weaken Russia and Iran. In The National Review article, he makes clear that the only kind of military intervention in Syria he would support is one that would “not be confined to Syria and would inevitably entail confronting Iran and possibly Russia.” Now that isis is largely vanquished, he argued last June, the focus of American policy in Syria should be “pushing back these Iranian and Russian gains” in the country as part of a larger effort to “begin rolling back Russia’s renewed presence and influence in the Middle East.” If Bolton has his way, Trump will use Assad’s latest chemical attacks as a pretext for a military strike aimed not primarily at saving Syrian lives, but at showing that America is still top dog in the Middle East. It’s hard to think of a more blatant violation of the “right intention” standard laid out in 2001.

For years, Bolton has yearned for a cold war with Russia and a hot one with Iran. Ever since taking office, Trump has yearned to show that he’s tougher and manlier than Obama and that he can make America’s adversaries tremble. Because Congress has abdicated its constitutional responsibility to declare war, Bolton and Trump are free to use Syria’s chemical attacks to do this. But the rest of us can, at least, not dignify it with the phrase “humanitarian war.
