since Trump is a Russian stooge who was put in office by Putin to deliver the victory

I am unsure. Logic tells me Trump has had enough opportunities to completely shit on Ukraine and has not taken them. His position is IMHO unclear.

strong demand for oil and gas benefits Russia proportionately far more than it does the US…

I disagree. Income for gas exports has not risen LINK whereas US exports continue to do so LINK

And “competitor” in what, exactly?

Geopolitical influence overall (e.g. in the Middle East, Asia, Central Europe)
