Foreign policy
Ryan has been primarily involved in budget matters and has little foreign policy experience.[57] Critics noted this, with former Democratic congressman and former ambassador to India Timothy J. Roemer telling Reuters: "I think his experience as a vice presidential candidate is thin; or for a future president and commander-in-chief, it's virtually absent."[58] Senior Romney adviser Eric Fehrnstrom defended Ryan, stating that his position as House Budget Committee chairman has given him intimate knowledge of defense spending and initiatives and adding that Ryan has been in Congress for 14 years, "longer than Barack Obama when he decided to run for president."[59] During his tenure in the Congress, Ryan has participated in seven trips abroad as a member of a congressional delegation.[60]
Reviewing the history of past presidential tickets, Jonathan Bernstein concluded that "depending on how one scores these things," Romney/Ryan is "certainly the ticket with the least foreign policy and national security experience since at least 1948, and perhaps as far back as 1912."[61] On the other hand, Senator John McCain and former House Speaker Newt Gingrich have compared the Romney/Ryan ticket's foreign policy credentials favorably with that of Ronald Reagan.[59]

Foreign and military policy
Ryan voted in 2001 and 2004 to end the embargo on Cuba,[147][148][149][150] but later reversed his positions, and since 2007 has voted against easing the embargo.[150] In 2008 Ryan told the Milwaukee Journal Sentinel, "If we're going to have free trade with China, why not Cuba?"[149]
Ryan was a "reliable supporter of the (George W. Bush) administration's foreign policy priorities" who voted for the 2002 Iraq Resolution, authorizing President George W. Bush to use military force in Iraq.[60] Ryan also voted for the Iraq War troop surge of 2007.[60] In May 2012, Ryan voted for H.R. 4310, which would increase defense spending, including spending for the Afghanistan War and for various weapon systems, to the level of $642 billion $8 billion more than previous spending levels.[151]
In 2009, Ryan termed the Obama administrations' "reset" of relations with Russia as "appeasement."[124] Daniel Larison of the The American Conservative wrote that Ryan "seems to conceive of U.S. power abroad mostly in terms of military strength" and "truly is a product of the era of George W. Bush."[124]
