Any major war abroad increases the level of authoritarianism at home. It gives a regime a reason to declare a state of emergency and to grab more power in controlling “subversives.” It’s obvious Trump wants and needs more power to protect himself from his growing crises. He’s already doing that by interfering with and politicizing domestic bureaucracies, but he can take the ultimate step and downgrade their significance by initiating a national emergency abroad. This would enable him to diminish the power of virtually all bureaucracies other than the DoD, which would conversely be elevated in stature (there’s a reason he’s got generals in the Oval Office). Maybe it’s a war with North Korea, or maybe it’s a war with Iran. It’s going to be a war with somebody. Donny has no conscience so he doesn’t care if people die, and it probably makes him feel more powerful to kill millions of non-European foreigners. That portrait of Andrew Jackson hanging in the background is Old Hickory’s ghost, egging him on to create his own modern version of the Trail of Tears.
