Donald Trump said frequently during his presidential campaign that he
did not want the US involved in all these expensive foreign wars.
Americans were lead to believe that the
US was finally realising that other countries should pay for the lion’s
share of any mutual defence; at their own expense. Trump also said that
he wanted other NATO partners to pay their fair share for any action
undertaken, the implication being that operational decisions will be
based on who has paid for what rather than what the enemy is doing—and
if the enemy is real or perceived.
