CHARLESTON, S.C. (Reuters) - Republican presidential candidate Jeb Bush called for an increased U.S. troop presence on the ground in Iraq as part of a global coalition to take on Islamic State militants, shifting to a more hawkish stance in response to the Paris attacks.
Bush's decision, which will inevitably lead to comparisons to the U.S.-led invasion of Iraq ordered by his brother, former President George W. Bush, was reached after the attacks in Paris, where 129 people were killed by gunfire and bombs.
"Radical Islamic terrorists have declared war on the Western world. Their aim is our total destruction," Bush told a conference hall filled with gray-uniformed cadets at The Citadel, a military college in Charleston.

Struggling to break into the top tier of candidates in the Republican field with Donald Trump and Ben Carson, Bush used an expansive national security address to present himself as ready to be commander in chief, saying the Paris attacks are a reminder that "we are living in serious times that require serious leadership."
Bush was vague on how many ground troops the United States should contribute to an international coalition that he says he would build if elected president next November.

President Barack Obama has relied heavily on U.S. air strikes against Islamic State in Iraq and Syria but recently sent 50 more special operations forces to help identify targets. He has said a massive reintroduction of U.S. ground troops in Iraq would be a mistake.
Bush said while air power is essential, it is not enough.
"The United States -- in conjunction with our NATO allies and more Arab partners -- will need to increase our presence on the ground," he said.

The effort will require "overwhelming force," Bush said, to take out Islamic State's self-proclaimed caliphate in parts of Syria and Iraq.
The scope of any increased U.S. presence on the ground should be in line with what U.S. military generals recommend and the bulk of the ground troops should come from "local forces that we have built workable relationships with," Bush said.
Iraq is a sensitive subject for Bush, given that both his brother and his father, former President George H.W. Bush, invaded the country.
Jeb Bush's plan calls for maintaining the U.S. prison in Guantanamo, Cuba, that his brother used for foreign terrorism suspects and which Obama is trying to close before leaving office in January 2017. The prison currently has 107 inmates.

Bush is eager to make an impact in a Republican race that in some respects has been leaving him behind. He is in single digits in many polls with Republican voters more enthusiastic about non-politician candidates Donald Trump and Ben Carson.
Bush's belief is that voters eventually will come around to a serious, policy-minded candidate like him but with the Iowa caucuses to kick off the 2016 election season on Feb. 1, his plan has not helped him in polls.
A Reuters-Ipsos poll found on Tuesday that 33 percent of Republican voters felt Trump would be the strongest candidate to deal with terrorism, followed by Senator Marco Rubio at 17 percent. Carson and Bush were tied at about 9 percent.
