Donald Trump is many things. But one thing he is not is a defender of the 2009-2016 status quo and accepted progressive convention. Since 2017, everything has been in flux. Lots of past conventional assumptions of the Obama-Clinton-Romney-Bush generation were as unquestioned as they were suspect. No longer.
Everyone knew the Iran deal was a way for the mullahs to buy time and hoard their oil profits, to purchase or steal nuclear technology, to feign moderation, and to trade some hostages for millions in terrorist-seeding cash, and then in a few years spring an announcement that it had the bomb.
No one wished to say that. Trump did. He canceled the flawed deal without a second thought.
Iran is furious, but in a far weaker—and eroding—strategic position with no serious means of escaping devastating sanctions, general impoverishment, and social unrest. So a desperate Tehran knows that it must make some show of defiance. Yet it accepts that if it were to launch a missile at a U.S. ship, hijack an American boat, or shoot down an American plane, the ensuing tit-for-tat retaliation might target the point of Iranian origin (the port that launched the ship, the airbase from which the plane took off, the silo from which the missile was launched) rather than the mere point of contact—and signal a serial stand-off 10-1 disproportionate response to every Iranian attack without ever causing a Persian Gulf war.
Everyone realized the Paris Climate Accord was a way for elites to virtue signal their green bona fides while making no adjustments in their global managerial lifestyles—at best. At worst, it was a shake-down both to transfer assets from the industrialized West to the “developing world” and to dull Western competitiveness with ascending rivals like India and China. Not now. Trump withdrew from the agreement, met or exceeded the carbon emissions reductions of the deal anyway, and has never looked back at the flawed convention. The remaining signatories have little response to the U.S. departure, and none at all to de facto American compliance to their own targeted goals.
Rich NATO allies either could not or would not pay their promised defense commitments to the alliance. To embarrass them into doing so was seen as heretical. No more.
