Why, after the disasters of Iraq and Afghanistan, would America contemplate sending ground troops into the Middle East again?

A: Because the POTUS is a desperate narcissist.

Trump's reality:

1. The war is very complete pretty much
2. Iran is desperate to make a deal.
3. They have given me a present.

Reality:

1. Iran is still fighting on all fronts,
2. Israel is still bombing
3. The strait of Hormuz remains largely closed
4. The Houthi have joined with Iran and could potentially block Red Sea trade routes.
