Trump announced in a tweet Thursday night that he would not attend the opening because of the new embassy's high cost and "off location" — an excuse that Hamill apparently did not believe.

"Very clever sir!" the Star Wars actor tweeted. "Cancelling the trip, rather than admitting you're scared-silly at the prospect of facing massive protests you'd inevitably encounter upon your arrival, was a masterstroke! UK is just another shit-hole country, right?"

Trump has faced criticism from leaders in the United Kingdom over a number of issues since his inauguration, and a planned state visit by the president has repeatedly been pushed back amid concerns over demonstrations.

In June, Trump reportedly told British Prime Minister Teresa May that he did not want to visit unless he had support from the public.

While Trump blamed the move to sell the embassy and build a new one on former President Obama, the decision to relocate the facility was actually made under former President George W. Bush.
