When I read the word “adversaries” I really wonder. In the 21 century are Europeans, Chinese and Russians adversaries? The whole planet as a matter of fact? Or do we have to accept that certain part of humanity needs to fight at any cost to the ecology and habitats of the planet regardless of what the rest of us, 7 billion people, think?
With the hypersonics we are talking about thousands of km/h, if we survive to the next fashion of megahypermagnetics we will still be caught up in the MATRIX. Humanity never learns.
“Whatever speed they may attain with this machine of theirs all the same. If they remain as they are not only they themselves but even their thought will never go any further than their atmosphere”
