Lol, like any US president needs justification for that ever. I mean it's a geopolitical event and the military-industrial complex certainly is one of the major lobby groups pushing for this (or any) confrontation, not disputing that.

But the immediate reason for Trump seems to be the (seemingly working) distraction from the escalating Epstein scandal. He already learned that war and the resulting market volatility is a great way to "flood the zone with shit" when he attacked Iran last year, and that being his primary objective also neatly accounts for the apparent lack of an exit strategy and clearly defined war goals.

Again, not saying it's the only reason why this war is happening in general, but probably the main one to Trump anyway. Which Warren seems to be confirming with her testimony here, saying there is simply no coherent reason presented for it even under secrecy.
