I really do not think nuking U.S will achieve anything by destroying countless of life, whatever the evil of U.S maybe.
I am sure if their was such plan, the plan has to be that U.S is nuke sufficiently that their is hardly any life left.
If their was any bases located outside U.S I doubt they will have a home to go back to after it has been nuked.
The logistics of trying to bomb the US to that point is staggering. If it could be accomplished by using 1 bomb for every 1,000 square miles of land surface That would take 9,634 bombs. Keep in mind Russia had over 30,000 nuclear weapons aimed at the US at one point, but they never reached the point where they felt they could achieve sufficient advantage to risk a first strike.
Most of the world thinks of the US as a country in terms of the country they live in. But, the reality is it would be much closer to think of it as 50 separate countries, although they all are United together.
As I said earlier it does make sense for people to think it would be fair to Nuke the US. This comes about because of what much of the world's perception of the US is. The country is seen as a land of great wealth, much extravagance and arrogance.
The world can not afford warfare in terms of military conquest. The world is ir need of conquest by truth, peace and love. Bombs are not going to solve any problems.
Some people do want to nuke the US and it is understandable that some people feel that way. But, the reality is it is not a workable solution. On the surface it makes sense for many people. But the overall effect would be to turn the people who would do so, into being the very same as what they are against. Everybody seems to agree that power and wealth corrupt, but at the same time it seems that many of those same people want it for themselves. As that is the type of power structure it would take for a government to have the initiative and ability for a first strike.
Total destruction of the US would only bring about a temporary change in the world balance. It would just mean that another nation would seize the immediate power gap and achieve world dominance. The game would be the same, except the players will have changed. Maybe for the worse.
