US has never won a war alone

Despite the self-professed role of the US as the guardian of freedom, democracy, human rights and the world order, and the huge sums of money it spends on its military, it has never led a successful campaign to achieve the goals it set for itself.

The US' unsuccessful campaigns in Afghanistan and Iraq have forced it to beat a (not-so-hasty) retreat, leaving the two countries in unprecedented chaos and ethnic and sectarian divide. The US was thoroughly defeated in Vietnam, Cambodia and Laos.
