The question of whether the US should, or can, sustain a foreign policy that is increasingly out of synch with the views of the people is one that should be taken seriously in a democratic country. If the American people have no appetite for further intervention, then that should be a major consideration for any president or policy maker. If those leaders believe the policy is essential for US interests or security it is their responsibility to build public support for that policy. A failure to build that support is a failure of leadership and ultimately of democracy as well.
