QUOTE : Isolationism appeals to every instinct we have to cut our risks and maximize our benefits, but it is dangerously naïve to believe that the world will simply leave us alone. No country can do more than America to lead an international fight against terrorism, and it must be done. Islamic State militants in Iraq and Syria can threaten the stability of the entire Middle East and could eventually promote terrorist attacks inside America and Europe. Washington can’t continue to ignore this region’s small problems until they turn into big ones. The United States can and should lead an international effort to ensure that ISIS remains isolated, even if it can’t immediately be dismantled and destroyed.
