Analysis: Trump nation-building view more in line with Obama

[...] it was Obama's predecessor, Republican George W. Bush, who committed the U.S. to large-scale nation-building projects in Iraq and Afghanistan.

[...] while the Republican presidential nominee argued against nation-building in a foreign policy speech Monday, he advocated for something even more grandiose: seizing Iraq's oil wealth in the aftermath of the U.S. invasion in 2003 that toppled Saddam Hussein.

In the final months of his administration, Bush negotiated an agreement with the Iraqi government that called for all U.S. troops to leave the country by December 2011.

Trump is right that the Islamic State capitalized on the political and security vacuum in Iraq in 2014, but it's not clear that a long-term U.S. military occupation to hold and exploit Iraqi's oil resources would have led to a more stable outcome.

Trump says he would have used money from the sale of Iraqi oil to pay for the care of wounded soldiers and the families of those Americans killed in the war.

Trump also called Monday for "extreme" ideological vetting of immigrants seeking admission to the United States, vowing to significantly overhaul the country's screening process and block those who sympathize with extremist groups or don't embrace American values.
