Each Friday, I look at what the presidential contenders are saying about foreign policy. This Week: Joe Biden doesn’t want one of America’s closest allies to buy a once iconic American company.

The war in Ukraine reflects collisions in Russia-Ukraine relations, Europe-Russia relations, and U.S.-Russia relations.

Proponents of retrenchment want the United States to do less overseas.

Last week, I had the pleasure of joining Jim Zirin on "Conversations in the Digital Age" to discuss U.S. immigration and the U.S.-Mexico relationship. Recently aired, you can watch the interview here.
