Nuclear powers in the world today in order of ability to destroy their enemies is as follows:
USA
Russia
England
France
China
India and Pakistan
The first four have the ability to destroy their foe into a no longer functioning nation even if they are destroyed. China in the future and near future can also achieve this status if they desire so. India and Pakistan are of no relevance as if they go to nuclear war it will be regional.
Iran is the real wild card. If they become nuclear which I suspect they are today they can rain hell down on the middle east at which point Israel will destroy them and much of the middle east. Israel will also hit Russia as the old USSR and present day Russia supports those that oppose Israel. Israel has this ability. This could actually lead to all the world powers engaging in intercontinental nuclear warfare.
Israel at this point would have nothing to lose as they would know full well their nation is destroyed. It is called the “Samson Option.” Most fortunately this will be confined to the middle east if we are lucky. Pray the Mullahs are not insane but I fear they are.
Mutually Assured Destruction is alive and well, pray the Mullahs in Iran regain sanity.
I left Israel out of the list above. We really do not know what they have. They do have the designs of our best weapons but that is another story. I assure you their nuclear arsenal is most robust. Israel never says what they have but their enemies no exactly what they have. Israel told them what they have.
“enemies no”
Should read as “enemies know” I had an attack of stupid fingers again.
