Childish response.
First, there is no love or compassion in geopolitics, its all interests.
Second, Let me clarify your delusions about India. Right now, India is used a transit for Russian oil for the west. Its serves Russian purpose to keep the energy leverage over west, otherwise, all that can be easily diverted to other markets like huge Chinese market.
Thrid, Right now, Russia needs Iranian support with its ongoing war with west in Ukraine, Unless you been living under the rock, Iranian support has been very extensive. Israel has got ZERO value towards Russian geopolitical interests right now as its sits among the western aligned nations. In other words, Israel is dispensable. Hell, Russia placed its nukes in Belarus with hardly any returns as when compared to Iran and its strategic value
Fourth, north korea dont give monkies to anyone, whoever pay the right price, will get the stuff from them. They are not bound by "holy land" attachments and sentiments. They wont care if Israel turn into dust. And do you think China would care? No one cares when American bombs are getting dropped all over civilian settlements, America is not held liable, and here its not even Chinese, we are talking about North Korea. And what do you even mean by China being liable? by whom? Do you think China being a super power cares? It bloody beat the crap out of another nuclear power India into submission and occupied Indian controlled territory with the rest of the world including Indian's sugar daddies in west watching in awe.
Lastly, you dont go about pinging a nuclear power's strategic locations with missiles and do not have solutions ready to deal with worst case scenario (we presume Israel is nuclear power). It is clear by now, that Iran didnt use warhead with its missiles and it was just a show of strength, telling Israelis that we can breach you raw and next time, those fireballs dropping over Israeli soil might be carrying something nasty. So , the delivery mechanism, its breach of Israeli defences, all confirmed, functioning without any shadow of doubt. Only guessing is if those missiles can be mated with nukes.
Its simple common sense, apply it next time.
