I think you'll find the ATACMS missile guided itself, based on inertial navigation and satellite positioning data. If your argument is that the United States guided the missile because the US provides GPS, that's a pretty flimsy argument.

Ukraine would have folded within a few weeks without the weapons systems of the combined Western nations. The Biden administration has given Kyiv permission to use U.S.-supplied missiles in Russian territory in a major escalation that now threatens nuclear war due to the first use doctrine updates. A few hours ago reports of UK Storm Shadow missiles being fired into Russian territory emerged. The West is at war.

By that logic every dictator t72 field trip would make Russia participant in that local war... Absolutely absurd statement. Siria civil war would see Russia waging war on Russia since their equipment was in both hands. What a contrived statement that the arm provider is at war itself.

The passive voice is doing a lot of work here.

Who is now threatening nuclear war?

As far as we know Ukraine both put them there and guided the missiles. Please provide proof otherwise.

Why do folks like your self make such foolish analogies? If the US had invaded Mexico like Russia invaded Ukraine then yes, it would be completely fine for Mexico to fire missiles into the US.

Russia took land from Ukraine. For how long do you think Ukraine can fire missiles into Russia?

As long as they're able to, until they get their land back.

What about México then? The US took 55% of the country, not only 20%.

Pretty sure we are talking about Ukraine and Russia here, not other conflicts.

You joined a discussion inside the discussion that was about Mexico firing missiles at the US. If you don't want to discuss similarities of both scenarios, don't join the discussion.

When people say "unprovoked" do they not know the history, or they think the history doesn't matter, or do they just not care?

Or they know the history all too well.

What did Ukraine do? Just exist ... menacingly?

Actually, that’s probably the key insight. A democratic, successful Ukraine (not a guaranteed thing at any point) would be an existential threat to the “Russian World” narrative from Moscow, and upend the regime. Even a partially successful Ukraine with working if imperfect pluralism, and regular transitions of power would probably be an profound threat, proving that other models could work.
