USA and west they are not countries or nations "by default order "

They are just the envoirement conditions playground for all the different groups business corporate and political groups to force their own agenda.

They are without face without idendenty they look like how the stronger group rules they change the face and they got no name whoever group or political group are in power that way they will look like.

China russia or any other who might be against west some how some ways can only destroy the political or corporate groups and try to get other groups in power but they cant destroy the west never it's like camelon whos changes the color it depends wich group is on power the USA is like milk house for groups each group come into power and use it to milk it same goes for all the west.
Western countries are just capitalists playground when business financial and corporate laws are like the constitutional first base laws.

So west is like the empty shell the host and whoever got power will come and use that host their own ways.

In terms of collapse or crash of usa theory or any of them like UK or eu Nations in the west..... The country woun't fall it will be just the political group or corporate group or another group who fall and will be replaced by stronger smarter and more powerful agenda wich later will be replaced by another more better and smarter stronger group.
War against USA means only one thing WAR against spefic group who rule USA but not to against USA.

For example USA is like exchanger with just few set of rules and political groups and other groups like traders who play with rules If they do good they win the game.

The face of USA can be anything it all depends wich group is on power.

Russia had war against biden rule not against usa the biden Lost that war means he removed.
If USA goes war against anyone it means If usa lose the political group will lose who rule that time there not all the USA
In other words USA UK canada eu and other west they not the Nations but the playground for strongest to make themselfes richest then taking out the wealth when another group get in power like Biden moved out wealth to china once trump got in power.
