Which specific ransomware attacks by the US and Israeli governments are you referring to?

The difference is that - Stuxnet aside - Western nations (including Israel) do not run cyber extortion schemes against random individuals and companies.

They do run intel campaigns against targets or sell the tools to run such campaigns, but so does every somewhat developed nation in this world. Intelligence operations are older than the Bible, they have been a part of civilizations ever since civilizations existed as a concept.

Us and isreal only target specific orginizations. If you are not a 'terrorist' you won't have to pay and probably won't even notice them.
