MIAMI (CBSMiami) – Republican presidential candidate Jeb Bush cites the Paris terror attacks as a reason for broad military build up.

The former state governor says U.S. armed forces have been left ill-prepared to defeat the Islamic State, which is blamed for the Paris attacks that killed at least 129 and wounded hundreds more.

“The brutal savagery is a reminder of what is at stake in this election,” Bush says in excerpts of a speech he plans to deliver Wednesday at The Military College of South Carolina, known as The Citadel.

Bush plans to pitch himself as a potential commander in chief able to handle such challenges, as his presidential bid tries to gain traction in a primary campaign likely to be shaken up after the Paris attacks.

“We are choosing the leader of the free world,” he said, according to passages released in advance of his address. “And if these attacks remind us of anything, it’s that we are living in serious times that require serious leadership.”

The speech, which had been scheduled before Friday’s deadly attacks, initially was to be more focused on Pentagon policy and equipment procurement reform. But the attacks prompted a quick shift in focus.

Bush hinted at the themes while campaigning Tuesday in South Carolina, where many Republican primary voters are retired and active-duty military, and where support runs high for the U.S. armed forces.

Bush has long faulted President Barack Obama’s administration, and former Secretary of State Hillary Clinton — the leading Democratic presidential candidate — for allowing wholesale federal spending cuts prompted by the 2013 budget reconciliation after Congress and the president were unable to craft more strategic cuts.

The cuts affected military and non-military spending alike, at a time when conflicts in Syria and Iraq “spiraled out of control as President Obama and Hillary Clinton failed to act,” Bush said.

Bush’s campaign Tuesday released a broad outline of his proposal, to restore the cuts and set goals to build up the military in several areas.

Many echoed points he has made over the past six months as a candidate, such as providing military training and support for allies in Eastern Europe and the Baltic region, where Russia has been applying pressure.

It also included some new points, including Bush’s desire to update the United States’ nuclear weapons capacity. Bush also calls for increasing production of next-generation stealth bombers.

And he also calls for doubling the U.S. Marine Corps’ battle-ready strength to 186,000.

“I believe in the principle that the greater our superiority in military power, the less likely it is that we will have to assert that power, or be provoked into using it,” Bush said in the excerpts.

Bush, a year ago viewed as the likely front-runner, has failed to move to the top tier of GOP White House hopefuls in a field where political outsiders Donald Trump and Ben Carson and charismatic young lawmakers Marco Rubio and Ted Cruz have eclipsed him.

But Bush hinted Tuesday, campaigning in Columbia, that the Paris attacks could change the focus for choosing the next commander in chief.

Bush also appears to be anticipating criticism that he would wage war in Iraq, as his father and brother did when they were president.

“I think it’s important for the next president, whoever he or she may be, to learn from the lessons of the past and use those lessons to focus on the future,” Bush told an audience of more than 300 at Coastal Carolina University in Conway Tuesday.

On Thursday in New York, Clinton will deliver an address outlining her strategy for defeating ISIS as well as her overall plan for fighting radical jihadism.
