This week's NATO Summit meeting in Wales will be among the most consequential in the Alliance's 65-year history. President Obama and Europe's leaders will contend with three major challenges.
First, they should agree on stronger sanctions against Russia following the move of Russian troops across the border into Ukraine during the last week. They should also agree to provide military equipment to the embattled Ukrainian government so that it can defend its country. Second, the European allies should agree to help the U.S. contain ISIS in Iraq and Syria. And, third, NATO should reconsider its decision to remove all combat forces from Afghanistan by the end of 2016. That will give the Taliban an open road to destabilize the new Afghan government.
These crises pose major challenges to this generation of NATO leaders. NATO will need strong American leadership, in particular, if it is to succeed in maintaining its status as the world's most powerful and effective alliance.
