Yea, right. America is pulling out of the gulf, and I'm the Queen of Sheba. The Unknowing Sheeple of America (USA, for short) will believe that until those dirty rotten Iranians start lobbing missiles at Israel, and (surprise, surprise) we suddenly realize that those hardened military bases we've built in Iraq are oh-so much more convenient than operating out of Diego Garcia. Oh. What?? Wait a minute.... Oh yea; that's exactly WHY we've been bothering with this little foray in Iraq. You can believe whatever you want, but DOD has no intention of abandoning the structures of our occupying presence in that area, that have come at a cost of 3 Trillion dineros.
Our nation needs to experiment with a little exercise known as waking up. Iran has built a Naval base at the Straits of Hormuz. Syria and Libya are rolling out the welcome mat to the Russian Navy, just as that Navy is being evicted from the Ukraine. Iran intends to begin launching against Israel ASAP, with a lot of help from N. Korea, Russia, and a cast of other characters.
Closer to home, Venezuela is working a nuclear deal with Russia right now, and the Russians are back in Cuba. Johnny certainly will be marching, but he's not coming home.
As for the domestic ammo supply, get 'em while you can.
