(CNSNews.com) - When Republican Mitt Romney said in one of the 2012 presidential debates that Russia was America's greatest "geopolitical adversary," he was right, said Rep. Paul Ryan, Romney's running mate.



Interviewed Tuesday night by Fox News's Martha McCallum, Ryan said, "You know, there are moments, Martha, when I just look down, shake my head, and say I can't believe we lost to these guys. This is one of those moments. Mitt was right.



"I think the President was incredibly naive on his Russia policy. His reset has been total failure. I think this is what happens when a superpower projects weakness in its form in defense policy. Aggression fills that vacuum. And I think that's what happening right now."





Ryan said he thinks President Obama doesn't support the traditional view of the United States as a superpower.



"I believe he's taken on the whole notion of exceptionalism. I believe we are an exceptional country for lots of reasons. And I'm not sure that he's going to be leading like he ought to be in this situation. Look, Russia's violated the sovereignty of Ukraine. I think there are a lot of things we need to be doing to address this, LNG export, other kinds of sanctions, but I think the lack of a coherent foreign policy, the fact that the president is proposing a budget to highlight our defenses projects weakness."



The president's $3.9-trillion budget proposal, released Tuesday, includes reductions in troop strength in every military service, active and Reserve.



Ryan described the president's budget as a "campaign document" for Obama's "liberal base."



"This is a budget where the president basically raised the white flag and has surrendered his administration for the next three years, and he's not going to do anything to address our fiscal challenges. I mean, last year he actually put a couple ideas in the budget to try and deal with our entitlements and our debts. This year, none of it, actually just more spending, more borrowing, $1.8 trillion in new tax increases, in addition to the $1.7 trillion he already put out there, over $8 trillion in more debt. His budget proposal (would) bring our debt up to $25 trillion. It's gone further to the left.



"So, this isn't an attempt to work with Congress. I think it's a campaign document for its liberal base," Ryan said. "It proposes that we never ever balance the project. And I just don't think American taxpayers deserve that. I don't think that's what they're looking for our president."



Ryan noted that House Republicans have passed three budgets in a row that balance the budget and pay off the debt. But with divided government, those ideas won't go anywhere -- especially if President Obama refuses to compromise.



"In this particular divided government, we're just so far apart," Ryan said. "And this president has moved far to the left. He's not moving to the middle. He's far to the left."



Ryan says Obama's budget would increase spending by $56 billion in 2015 above the Murray–Ryan spending agreement that he signed into law just two months ago. And on top of the $1.7 trillion in tax hikes he's already implemented, the FY 2015 budget requests another $1.8 trillion on top of that. Roughly half of the new tax hikes would be dedicated to new spending rather than deficit reduction.
