We were funding and arming the terrorists in Syria...we were ready to send our own military in until Russia interjected.
Not really, the Free Syrian Army were quite moderate in comparison to Assad, Al-Nusra, ISIS and were just one side of a particularly brutal civil war. The notion that they were the terrorists is quite inaccurate. By not supporting them we actually made them the weakest of the four main sides in the conflict which allowed IS to gain the most ground. In fact, Assad has probably done more funding and arming of the terrorists fighting him than we have.
Iran is not what they are focusing on right now.
Do you honestly believe they will leave Iran alone ?
Iran will be invaded just like Iraq was and then over time they will split it up the same way they are going to do in Syria and Iraq.
keep the countries smaller and weaker....easier to invade.
They've left Iran alone for 35 years and I don't see why that would change. Relations between the US, Britain and Iran have actually been improving recently with the change of Iranian president. What effect the present situation in Iraq will have is anyone's guess, maybe I'm just being too optimistic in hoping that we'll emerge with better relations.
