"It’s time for Obama to make a choice: Lead us or resign"
This fails as a false dilemma fallacy, in addition to being a ridiculous lie.
Leadership involves making the correct decisions, such as the correct decision to not send Americans to once again fight and die in a meaningless, never-ending war in the ME.
Indeed, pursuing the proper policy when sustaining unwarranted, baseless attacks from the political opposition is to very much exhibit leadership.
Consequently the president is providing leadership, where to maintain otherwise is an inane, partisan lie.
