Bearing in mind that Nick’s starting comment was about America joining Russia to invade Iran etc if Britain fell, it should be noted that, because Britain didn’t fall, America invaded Australia instead, and it was worse.
For example, America had about 1,000,000 troops in our north eastern state of Queensland, which before the Americans arrived had a state population of about 1,300,000. Given that a lot of our men were elsewhere in uniform, a million Yanks plus about half a million Aussie blokes competing for about 600,000 to 700,000 women caused a degree of friction, but not the type commonly sought by soldiers on leave.
