Interestingly, after Romney went off on a tangent yesterday, John Boehner says people shouldn't criticize the president while he's overseas. I kind of like that respectful talk. It's respectful of the president, the office and the nation. Other than that, we don't need the republican path of engaging nations. We don't need Mitt calling Russia a "geopolitical foe." What's that supposed to mean anyway?
There's a ton of background and fact sheets at WhiteHouse.gov on the Nuclear Security Summit, if you're so inclined. It's stuff you're not likely to see in the news.
