I don't want to make too much of this, since the American people remain anti-interventionist in terms of military power, but there has been a modest uptick in opinion favoring deeper involvement abroad. A new Pew survey finds this, along with 54% saying President Obama is "not tough enough."
Of course, support for toughness is not the same as support for military intervention. I think the poll reflects the numerous, simultaneous, and quite serious problems in the news. Americans want a stable world, not one in turmoil.
