I’m concerned, for the same reason they are, nobody wins a nuclear exchange. With us supporting and guaranteeing Iran, a preemptive strike is very unlikely. Even lynching Lurch wouldn’t change that.
The only way to have prevented a “nuclear exchange” (by which I assume we are including weapons far more “advanced’ than that old stuff!) was for USA to remove the Iranian IslamoNazi threat.
Since O has made it clear now what he’s been doing (protecting and financing his Iranian IslamoNazi comrades’ buildup of nukes with ICBMs to attack America)....
all we can say is... duck and cover! (not that it will do any good)
