Regarding Russophobia, the pattern is older than any US involvement. The US/NATO are the first arming the Ukrainian army themselves. Formally the Budapest Memorandum binds the US and UK to supporting Ukraine.
We have to see how the future will be and do our best to support Ukraine and similar places. It is true that we should be cautious regarding the US intentions. Russia's own actions and history sadly made it a far worse option prior to any involvement from US/NATO.
