Trump wants to attack Iran and ends up helping them more than ever. And Russia can also sell more oil at a higher price now. Great job. He went in without a goal, plan or exist strategy, and it really looks like he'll end up strengthening Iran.
At least I hope that Russia's support for Iran and Ukraine's support for the Gulf states, ends up finally driving a wedge between Putin and Trump. But in every other respect, he's just strengthening authoritarian regimes.
