WASHINGTON (CNN) - Mitt Romney, eyeing a run at the presidency in 2012, is taking another step in fleshing out his foreign policy portfolio with a Monday speech to the conservative Heritage Foundation on the topic of defense spending.
According to excerpts of the speech provided to CNN, Romney will call the Obama administration's plan to trim more than $1 billion from missile defense programs a "grave miscalculation" that will put America at risk, especially given North Korea's nuclear provocations.
Romney says that Obama should push for "comprehensive, regime-crippling sanctions" against North Korea and "immediately reverse his recent decisions and strongly support completing our ballistic missile defense system."
In the speech, entitled "The Care of Freedom," Romney will also call on the administration to increase the modernization budget by $50 billion per year and to lock in total defense budgets at no less than four percent of GDP. But the military budget has been endangered, Romney argues, by the administration's domestic spending programs.
"Over the last few months, it has passed measures that will add almost $4 trillion to the national debt in the short term and then over $3 trillion over the next ten years," Romney will say. "None of that money was spent on increasing the defense modernization budget - a failure that history will never understand or excuse."
The former Massachusetts governor is urging pro-defense members of Congress to hold firm against further cuts. He plans to say that "depleting the defense budget to fund new social programs, particularly in the face of global turmoil, would put America and Americans at risk."
"At the most fundamental level, our military might depends on the long term strength of our economy," he will say, according to the excerpts. "The President's planned budgets and multi-trillion dollar deficits, financed by a level of borrowing never before attempted by any nation, puts our whole economy in jeopardy."
Romney, who ran the investment firm Bain Capital before entering politics, often touted his business and managerial experience as a presidential candidate. But as a former governor, he had limited experience with national security matters - a deficit that his rival John McCain was eager to highlight during the primaries.
Since the 2008 election, Romney has re-emerged as a vocal critic of President Obama's security agenda, and has made a series of public statements aimed at raising his profile in the foreign policy arena.
In April, he blasted Obama in The Weekly Standard for not objecting when Nicaraguan President Daniel Ortega criticized the United States at the summit of the Americas in Trinidad and Tobago. "President Obama shrank from defending liberty here in the Americas," Romney wrote.
Last month, when Obama and former Vice President Dick Cheney presented dueling speeches on the use of enhanced interrogation techniques against suspected terrorists, Romney defended Cheney and said that Obama's speech "was more tortured than the enhanced interrogation techniques he decries."
Romney has said he will not hesitate to praise the president when he agrees with him. At an April fundraiser for Senate Republicans, for instance, Romney applauded Obama for taking the right steps in Iraq and Afghanistan. But despite those kind words, Romney has so far been more critical than supportive of the administration's foreign policy agenda.
