1 Do you mean, paying the Aya-tolls? (Sorry, just couldn't resist that.)

2  With this move Trump has China by the short hairs. Almost 50 % of Chinas oil comes from this area. 38% from OPEC and another 17% from Iran then figure its lost sales from Venezuela that comes to roughly 50%.  Xi brought this on himself with the arrest of his 2 top generals. This tabled any Taiwan invasion plan and then shelved the plan with the arrests of the generals subordinates, the people whose job was to execute the invasion.Trump got revenge for his failed assassination attempt by killing all those who tried to kill him. As far as regime change thats not part of his plan, if it was Trump would have never allowed the reinforcements   to parade themselves into Iran from Iraq and Afghanistan unmolested. If not for the global market our oil prices would still be reasonable and would not have spiked as did global prices. We only get 13% of our oil from OPEC. Not a small amount but easily replaced. 

3 Dana LMFAO!  That was a good one!
Agreed Mike; that's why I say it's a pleasure to watch Trump work. He always has the angles covered when he does anything. Sadly most Americans will not ever think of this.
