Lately democrat admin allowed Ukraine to hit Russia with Usa equipment like atacms. They already use drones and similar systems of their own it wont make much difference in Kursk for example.
However if Usa-democrats give longer range lrasm cruise missiles to Ukraine and tell them to hit Moscow then it would be a very big escalation. As mentioned previously in the thread if Russia uses tactical nukes it will open a new chapter in other conflicts worldwide where tactical nukes will be available for them as well. Also Russian army mostly concentrated in SMO zone will be hit from Ukraine airspace by any third party like a massive cruise missile attack like for example missiles launched from sea or a neighbor country and Ukraine can claim responsibility for the attack. In return a large scale Russian nuclear attack can happen to Ukraine to stop the cruise missile attacks but as a result Russian army will be highly damaged from the attack.
Russian allies who have sufficient air defense like Iran and China can install short range air defense line south of Moscow. That would protect Moscow and Saint Petersburg. In return Russia can agree on lowering any conventional reaction against Kiev, Lviv regions outside of Smo zone and use large scale bombs like fabs-odabs defensively like in Kursk for example and use them much less in Smo zone. These kinds of moves can deescalate the conflict for both sides. The point should be the move should also deescalate Russian moves against Ukraine at the same time increasing protection of Russia against these types of attacks.
Also if they put Russia in a difficult situation when trump comes next month or so then trump can make a deal with Russia against Iran or even China maybe. Defensive moves like above will block any trump deal with Russia to stop conflict with Ukraine and in return get concessions from Russia against Iran.
Otherwise since usa is powerful you can trust democrats and believe in whatever they say for a month or two and hope trump will not make a deal to end conflict with Russia and in return get concessions against Iran or China. That is foolish and lack of thinking in my opinion.
