Correct. Anyone remember the time the US drafted the "The Netherlands / The Hague invasion plan"? Target of invasion? The International Criminal Court, if America of US soldiers were ever brought before trial for war-crimes. Seems International means non-us.

Hell, they overthrew the elected Prime Minister of Australia because he abolished the military draft, pulled Australian troops out of Vietnam, and was threatening to forbid the renewal of the lease for a US military base.
The right to self-determination is really only something America enjoys. When it needs to, it imposes its will upon other countries, often in the most cruel and twisted possible way.
Gough Whitlam was fired in 1975, as the US was pulling out anyway. He was fired because the Senate had blocked supply, and he was trying to secure alternative funding (which just isn't done). Kerr (the Governor General, who was mostly a figurehead but is technically the acting head of state) and Fraser (leader of the opposition) both suggested compromises. Whitlam thought that he didn't need the Senate or GG's cooperation, and that the whole "Westminister system" was a formality he could do without. So they sacked him.
tl;dr - there was a Constitutional crisis, with the House and Senate disagreeing. The Prime Minister didn't want to negotiate, or call for a new election, so he was removed.
