We had already been aiding Ukraine militarily in Trump's term, you moron.
Putin's invasion was an act of war against a nation we had good and supportive relations with and one on good terms with all our NATO alliies, you moron. Yes, Putin's invasion was and is of concern to all our NATO allies in Europe. To pretend what concerns them very much does not concern us denies the meaning of that alliance. If that's what you want to do, then say so, but quit pretending that Putin's invasion of Ukraine should not concern anyone in NATO, Mr Chamberlain.
