INCLUDES THESE SUBS

Bradleys most certainly changed the course of the war. It's not always about firepower, either. This war is showing how all tanks are being defeated with drones. We're in a new era of warfare. Like u/Dune1032 stated, Ukraine is being used, in part, as a testing ground for old (and probably some new, un-reported) technologies for the U.S. with no official troop losses for the U.S.

The US will be supplying Ukraine with more ATACMS. This will force Russia to move their supply depots further back making it difficult to sustain an attack.

Russian air defense is more than capable of shooting down anything and everything Ukraine can fire at them, especially ATACMS. Even the dreaded Stormshadows have gone from a serious threat to a minor threat as the Russians have learned how to destroy them. Not every single missile, but enough to prevent Ukraine from doing major damage.

When those ATACMSes get close enough to the front line to actually threaten Russian forces, they will be destroyed, just like the previous batch of ATACMSes.

Ukrainian pilots should be trained on the F-16 soon eliminating Russian air superiority.

The F-16 is not a bad plane at all, and in the hands of capable pilots with many years of experience, they would almost be peer to the Su-35, but in no way is it superior to the Su-35 in combat. The SU-35 has already proven itself to out-class the F-16 in Taiwan. The SU-35 can blind the radar of F-16s, including the much-vaunted AESA, and force the F-16 pilot to retreat with his tail between his legs. The SU-35 is faster, more manoeuvrable, has a longer range and a much higher ceiling, it carries more weapons including potentially hypersonic missiles that the US cannot match. It can engage the F-16 from much further away than the F-16 can engage them back, and it has a smaller radar cross-section than the F-16.

But those F-16s aren't going to survive long enough to face off against SU-35s. They're going to be chewed to bits by Russian missiles long before that. Why do you think the Russians didn't put their pilots in the sky earlier, before they smashed the Ukrainian air defense? The same applies now, but in reverse.

Those Ukrainian F-16 pilots are dead men walking. Poor fuckers 😞

The Russians are not making huge gains as you claim.

Clausewitz on the purpose of war: "The aim of war should be the defeat of the enemy. But what constitutes defeat? The conquest of his whole territory is not always necessary, and total occupation of his territory may not be enough."

Russia is bleeding Ukraine to death, and demilitarising NATO. And they are doing so with remarkably few losses themselves considering the nature of modern war. They have already taken around one fifth of Ukraine's territory, and will take more when Ukraine is depleted of men and munitions.

You think Russians like fighting for Putin?

Ukraine has to send press squads into the streets to literally kidnap any man who is desperate enough to step outside of his house. They are begging the rest of Europe to deport the Ukrainian men who fled the country back. Meanwhile in Russia the army has so many volunteers that they almost don't know what to do with them. Especially after Ukraine started terrorist attacks against Russian towns and civilians. And that doesn't include the non-military volunteers contributing to the war effort.
