Building a fence is a strange move for the party of Ronald Reagan, whose call to tear down the Berlin wall ranks as one of the most memorable lines of the 20th Century.

It didn't take much conviction to decide Egyptian President Hosni Mubarak had to go after the Egyptian military turned on him.  Ditto for Libya’s Muammar Qadhafi, once large portions of the country had freed themselves from his rule and our European allies were clamoring for military intervention.  But when the outcome is in doubt, as in Syria, Barack Obama is sitting on the fence.

Up on Capitol Hill, there appears to be progress--bipartisan progress, even--toward changing our immigration laws to reflect current and emerging realities.

In the wake of the recent events in Afghanistan, sentiment is growing to speed the U.S. military exit. Half of the American people now want to get out faster, and Obama administration officials are reportedly debating doing just that. Which raises a critical question: What would happen if we pulled out of Afghanistan?

The stage now seems to be set for perhaps the final act in the Euro-zone debt crisis. With its economy literally imploding, social tensions close to the boiling point, and its IMF program woefully off track, there is every prospect that Greece will experience a hard default by year end.

What we need to do now is to create more openings for high-skill immigrants while reducing the number of slots for extended family reunification for low-skill immigrants, and Congress (though no the Obama administration) seems to be taking some steps in that direction. The Economist, while not addressing low-skill immigration, seems to be taking a similar view.

Local security forces do not offset the risks incurred by premature withdrawal of combat forces from Afghanistan. In fact, premature withdrawal of combat forces undermines the local security effort.

The United States has an enormous interest in seeing Mexico living under the rule of law.
