Americans should support the impeachment and removal of President Donald Trump, but not for Ukrainegate. In fact, they should oppose his impeachment on Ukrainegate grounds completely.
Trump's real offense is waging an un-authorized, unconstitutional, illegal, treasonous and for-real genocidal war against the human beings of Yemen. His war crimes in Afghanistan, Somalia, Libya, Syria and Iraq have at least taken place in conflicts supposedly authorized by Congress, making the legal cases against actions there somewhat more complicated.
But in Yemen, no law, only presidential orders, have authorized our military, spies, arms merchants and mercenaries to "lead from behind" in this disastrous war of the so-called "Saudi-led coalition" against the civilian population there.
The previous Yemen war, the CIA and air force drone war against al Qaeda in the Arabian Peninsula (AQAP), which began in 2009, the lawyers argued, was legal under the Authorization to Use Military Force against the group that attacked the United States on September 11th 2001. They were, after all, involved in the attack, and had previously bombed the USS Cole in 2000. Of course that drone war only backfired, empowering the al Qaeda enemy by radicalizing the local population. It turns out a 500-pound bomb isn't a "scalpel" in real life, like they say in Washington.
