“We believe that all the armaments we have from the United States of America are paid for, it’s not free armament. So ever since the relationship started between Saudi Arabia and the United States of America, we’ve bought everything with money,” Prince Mohammed added.

Last week, Trump repeated his insult to Saudi rulers three times in three election rallies in three states, asserting that the Saudi king could not stay in power for two weeks without the support of the US military and ordered him to pay the costs.
