Am I overreacting or does "we will financially ruin anyone organizing a peaceful protest" not logically lead to adventurism?
it logically leads to more than adventurism, it leads to whole organizations choosing to operate underground. He's inadvertently creating a market incentive for rebellion
I expect "Operation Prosperity Guardian" to be really boring actually. Yemen shoots a few drones at the coalition fleet, the fleet intercepts them with 4x as many missiles worth enough money to end world hunger overnight. Maybe they drone strike an abandoned firing position or elementary school in retaliation like they normally do. Rearm and repeat for weeks. No warships sunk but also still too dangerous for merchant shipping. Half measures all around.
Though ansar Allah could have some clever plan or just score a lucky hit, in which case we may have some decades happen. But tying down three US carrier groups is impressive enough on its own.
