Liberal foreign policy is indistinguishable from the neoconservatism championed mostly by conservatives. From Danny Sjursen at antiwar.com:
If anyone else were president, the “liberals” would be celebrating. After all, pulling American soldiers out of a couple of failing, endless wars seems like a “win” for progressives. Heck, if Obama did it there might be a ticker-tape parade down Broadway. And there should be. The intervention in Syria is increasingly aimless, dangerous and lacks an end state. Afghanistan is an unwinnable war – America’s longest – and about to end in outright military defeat. Getting out now and salvaging so much national blood and treasure ought to be a progressive dream. There’s only one problem: Donald Trump. Specifically, that it was Trump who gave the order to begin the troop withdrawals.
Lost in the haze of their pathological hatred of President Trump, the majority of mainstream liberal pundits and politicians can’t, for the life of them, see the good sense in extracting the troops from a couple Mideast quagmires. That or they can see the positives, but, in their obsessive compulsion to smear the president, choose politics over country. It’s probably a bit of both. That’s how tribally partisan American political discourse has become. And, how reflexively hawkish and interventionist today’s mainstream Democrats now are. Whither the left-wing antiwar movement? Well, except for a few diehards out there, the movement seems to have been buried long ago with George McGovern.
