Iran could offer to halt production of 20% enriched uranium in upcoming negotiations. This “concession” would have limited impact on Iran’s ability to quickly produce weapons-grade uranium for one nuclear warhead, however. Iran would still retain the ability to resume 20% enrichment and to produce weapons-grade uranium at a time of its choosing.

Barack Obama’s presidency has had profoundly negative consequences for our national security. From debilitating cuts in defense budgets, to gutting national missile defense efforts, to his unwillingness to acknowledge a continuing war against terrorism, to his inability to stem the nuclear proliferation threats posed by North Korea and Iran....the picture is bleak.

Obama is always willing to make a rhetorical concession to buy goodwill, but these concessions carry two serious risks.

If Romney can’t defend free-market capitalism against Gingrich, how will he be able to defend it in the fall against Obama?

Even those who have never negotiated with North Korea could have told the Obama administration, “I told you so.”

Heads of state and foreign ministers from 50-plus countries will gather next week in Seoul, South Korea, to discuss the threat of nuclear terrorism, a follow-up to the first “nuclear-security summit” convened two years ago in Washington by President Obama.

While strong support for South Korea following the tragic murder by North Korea of 46 sailors is welcome news, an unnecessary concession to China is less promising.

The need to rebuild and revitalize America's transportation system is unprecedented. But so is government debt, as well as the lack of public support for higher taxes. So the question is: Where will the money come from?
