Maybe President Trump discovered that Russian “advisers” in Iran used a Russian mobile launcher so send one of their surface-to-air missiles up to destroy the drone. I think this is a trap. It spells out a very dicey situation and requires a well-planned response. In short, Russia is involved in this. In fact, China is involved too.
That is as valid a conjecture as any I have thought of. (I didn’t consider yours)
For all of the demented libtard caterwauling about how President Trump will get us into some kind of shooting wars with Iran and Mexico; he has been remarkably restrained in foreign policy matters. Far more so than his Peace at Any Price predecessor.
