Let me guess: You're one of those people who said that the US Space Force "violated the treaty" because it "weaponizes space", right?

The treaty bans weapons of mass destruction in space. It does not ban military activity in space at all.

In some hypothetical hot conflict where a major belligerent nation had already started taking down satellites and/or polluting orbits, the treaty will have already become a 'dead letter'.

As long as they're not using nukes I don't think compliance with the OST would be an issue

Ripped up as soon as you started intentionally trying to create Kessler syndrome...
