How many cruise missiles have Russia fired into Ukraine? Is Ukraine disarmed? Tomahawks don’t grow on trees and the US already faces running out of ammo extremely quickly in any war against China. How many Tomahawks do you think that can afford to send to Ukraine to attack Russia without blowing up their own war plans against China?
Putin is not the president of China, he is the president of Russia. whether the US runs out of missiles in a hypothetical war against China or not is quite irrelevant to how Russia should respond to this American ballistic missile strike against the Russian mainland.
American ballistic missiles were
fired inside Russian territory. from what Scott Ritter says it is not possible for Ukraine to use these weapons without involvment from the US military &/or it's contractors in this strike. it would have been one thing if Ukrainian drones are what attacked Russia but it is completely different when American ballistic missiles are what's attacking Russia.
whether the missiles caused zero damage or massive damage doesn't change the fact that American ballistic missiles are striking the Russian mainland. Russia has to regain deterence by retaliating against these strikes. if Russia doesn't retaliate then that basically tells the US it is ok for American missiles to attack the Russian mainland.
I have seen some analysts suggesting that Russia could regain deterence by killing Zelensky. I believe that would not be enough. The US doesn't give a flying F about Ukrainian soldiers &/or politicians being killed including Zelensky. for them Ukrainian soldiers and politicians are just disposable tools against Russia and not some precious assets equal in importance to the importance of the territorial integrity of the US mainland.
if American missiles are striking Russian mainland then an equal retaliation would be for Russian missiles to attack the US mainland. obviously that would be quite difficult to do since no proxy of Russia in Latin America would be willing to help Russia to do that. so the next best thing to do would be to strike a US base inside a NATO country. that would be a sufficient retaliation since article 5 means an attack on a NATO country is equal to an attack on all (including the US mainland).
the least Russia should do as retaliation if they don't have the courage and/or capability to do the previous two options is to shoot down all NATO drones over the black sea and hopefully that would be enough to send the message to the US that it is not ok for American missiles to attack Russian mainland.
some people say this is a trap by NATO to drag Russia in a direct military confrontation and thus Russia should not respond to this provocation so as to avoid falling into this "trap". personaly I believe that line of thinking makes no sense and is quite dangerous.
the burden of de-escalation should fall on the aggressor not on the victim. if some one attacks you in the street do you go "oh I should de-escalate so I'm not gonna retaliate"? no of course not.
as I said Russia should retaliate and the burden of de-escalation should fall on the US since they are the ones who started it by violating the Russian mainland with American missiles. and if the US refuses to de-escalate and instead retaliates against the Russian retaliation then that is fine. and if the US continues to escalate against Russian retaliations against NATO territory till all of them reach nuclear Armagedon then that is fine too. it would be the collective west who have chosen nuclear catastrophy and not Russian.
