If Trump retaliates over a drone, he gives the Iran government what they want... pictures of injured Iranis at the hands of the Evil Empire... which will unite Iran against the US. By letting the sanctions continue, the people will continue to turn against their government... only this time, we will support them... unlike last time, when Obama left them to die in the streets. Agreed. Good diplomatic move by Trump. Let the world see he's giving them an opportunity to act responsibly without paying tribute. Everyone knows they can be crushed... so much better when their own people do it.
