I read that Russia accounts for 65% of Germany's natural gas imports. 65%! Doesn't this put your country in a rather disadvantaged position economically?

Putin supporters: Tulsi Gabbard, Tucker Carlson (the new Tokyo Rose) and Trump et al. Moscow Mitch and by extension, most of the Republican caucus. It will be interesting to see if Putin's rhetoric against Ukrainian Nazis generates any backlash among the Christian white nationalists.

The White House is rather supportive

I think your question has been answered by Buttercup who has spouted all the relevant russian propaganda.

Why would anyone applaud starting a war unless that person has something to gain or enjoys the suffering of innocent people?

Why would any decent person support a warmongering despot like Putin?

I don't support Putin or violence in general but the US seeking to further expand their already global military presence was an obvious and deliberate provocation. The propaganda demonizing Putin is unrelenting now in an attempt to drum up support for further involvement. I also believe Biden cynically expects this to help him in the next election.
