With all due respect , you dont have to use your weapons in a “Real” war to know how they work or in what situation is best to use them . We have many weapons that have never been tested in real conflicts . There are many reasons for this , some are too destructive , others are of a secretive nature , and open testing for the world to take note of , is undesirable . Rest assured , Russia and China know very well , what they have , and the best way to deliver them ……………..as we do . As usual , you can have all the toys in the world , but if your leadership is incompetent , they do you no good . Unfortunately , we have not known total victory sense 1945 . This is because of politics and poor leadership ,and the longer that kind of doctrine continues , the more vulnerable we become . Why ? Because the generals have never known victory outside a text book , or have any real experience of winning , outside theory . Good news is , at this point , either does Russia and China . Everything is theory at this point , if the real thing were to take place , there are going to be plenty of rude surprises to go around on all sides . Its how fast the other can adapt that may make the difference .
