In between campaign stops across the country as presumptive vice presidential nominee, Paul Ryan has been studying up in an effort to boost his foreign policy knowledge.

Asked about Russian and Chinese power in a radio interview with host Mark Levin Wednesday night, Ryan  focused his response only on U.S. participation in the United Nations Security Council and the country’s looming $500 billion in defense cuts. (Ryan helped set those cuts into motion by casting a “yes” vote on last August’s debt-ceiling deal; he says he was voting for the process, not the policy.)

“The Obama foreign policy is to subjugate ourselves to the United Nations, which gives Russia and China a veto power at the Security Council," Ryan said. "So we are giving these two countries you mentioned -- these two powers who do not share our values -- undue, needless unnecessary clout because we’re running everything through the security council. That’s point number one.”

“Point number two," he added, "is these reckless defense cuts that the president has promised in his budget and his lack of leadership to deal with these devastating defense cuts that are coming at the end of this year means we will have a Navy that is so small we haven’t seen it since the likes of the era of the 1917 time.* That deals with the issue of the South China Sea in the Pacific. If we do not have a strong Navy, we cannot protect our interests globally.”

* Politifact has rated this claim on the size of the Navy "Pants on Fire," noting that there were fewer active ships under President George W. Bush.
