wikipedia based on US scientific charts.. says the Russian sarmat nuke
with a 10 ton throw weight , can be armed with a single nuclear warhead from 50-60 megaton. Which is pretty descent.. much more than what US military can achieve.
Considering US biggest nukes are Tridents 2 of 5-6 megatons only..
So Russian sarmat can hit as hard as 10x trident missiles.. which is pretty descent.
and about 150x times times more powerful than the amateur nukes Israel have in their
latest Jerico 3 intercontinental missiles.. estimated at just 400kt nuclear warhead..
Only Thing Russia needs to do is mass produce them.. replace all their Satan 1 missiles with Sarmats.. and it will be ready so send to the stone age literary any hostile country..
every inch of its territory.
To wipe a country like Israel ,a state that most of it is empty.. Any "small" nuke of 20kt in a commercial city , will be enough to finish Israel as a functioning nation. you nuke one city ,lets say an economic zone ,like Telaviv and everyone else in the country ,will not want to stay there , waiting for more attacks... will just pack and leave.
The radiation fallout and the psicological impact of the attack ,will finish the rest of the country.. if destroy a nuclear reactor.. it will be chernobille part 2.. Not many people , Scientist and business with families and children will want to live in a place that was nuked and radiation get people ill and with cancer.. this is more true if the attacking country and the victim never restore relations .. Japan could only move forward because US and Japan restored relations after a complete surrender by later.. and so confidence in a better future was not lost..
