When else in history have there been big protests in the US regarding unrest or war in other countries?

The US doesn’t have soldiers fighting in the current Israel Palestinian war, but there are protests in the US about it. The US does have troops in other parts of the ME getting attacked and some retaliation has happened. The US also supplies some weaponry to Israel.

The Vietnam war eventually led to protests in the US, but the US and our soldiers were directly involved in the war (conflict).
