The USA wants to withdraw from Afghanistan, preferably on their own terms, but if not possible then on somewhat acceptable terms. President Trump isn't a fool despite what many people would like to think, it isn't Trump alone, the republicans are behind him, the ones in the republican party who matter are in unison with President Trump. They want to win the next elections and withdraw from Afghanistan. They are bleeding billions and billions in Afghanistan and more importantly, the American public is extremely tired of wars.
A large majority of United States military personnel come from about four or five states. People need to understand that the American public has begun to hate the war in Afghanistan. This is something way beyond Vietnam weariness!!
The chances are that President Trump will successfully end the war in Afghanistan.
