You wish.  Obama's Iran Nuclear deal went a heck of a long way to establishing good, verifiable, deftly negotiated diplomatic solutions to de-weaponize Iran's nuclear capbilities.  It resulted from a combiination of good statesmanship by the President and an effective State Department.  Trump is giving China and Russia the position to make demands on US foreign policy and make us look like a bunch of bozos,  directly raising tensions with his little boy dreams of being an army man approach to  foregin policy and tweeting, and  forcing a military endgame with a nut that possesses nukes and an alliance with a China concerned over the impact on its own border.  Think about this:  Trump, the titular commander in chief, making decisions about waging war and placing American military lives at risk.  Really scary.  Mostly because he looks like a fool,, and we know he doesn't react well or rationally when he puts himself in that situation.
