The only way to be rid of them is strike hard, like Africa & North Vietnam. If you fight back they make a great noise & thrash out, if you don't they take you apart to ownership. Nothing is achieved giving them anything to go away.
Their London Embassy complex is on the river like MI6 to stealthily move to & fro. Buildings either side are flattened to subvert communication intercept & the nearby tube has US staff & a private entrance.
