The perception that the US is a threat to world peace is far from uncommon, especially in the Global South, and I do agree with it based on historical and geopolitical precedents set by the US over the last several decades. Two examples demonstrating that this view is quite common:
Belief in importance of democracy high in 53 sampled countries but inequality and big tech companies seen as biggest threats

Across 30 nations, a median of 38% now say U.S. power and influence poses a major threat to their country, up 13 percentage points from 2013.

That said, I see the US' support for Ukraine as a significantly positive thing, and I agree with helping Ukraine fend off Russia's imperialist, hostile invasion. What NATO is doing seems to me the best approach because it helps Ukraine while avoiding escalation into a third world war via direct confrontation with Russia.
