Iraq got a new Shiite government under Bush — years before Obama came in. the new leaders, who replaced Saddam, were Shiites who’d been living in Iran in exile, when Saddam was in power. Iraq became an Iranian allly when these guys took over the government.
and all that happened when Bush was president.
Interesting, but academic, since the policy toward Iraq and the diplomatic and military strategy completely changed with Obama and affected the behavior of the Iraqi government, regardless of who was in charge. Obama’s behavior left a void filled by Iran, especially after he dragged his feet to assist against ISIS, allowing Iran to get even more influence over Iraq (which apparently they were fine with based on reports of the diplomatic efforts)...and given his behavior on the nuclear deal that only increased their power in the entire region more - none of these moves would have been made by the Bush administration. You have no credible rebuttal to my point.
