I believe that Poland is right to armor itself up because there is nothing better for peace than a strong deterrent.
However if Poland moves its own troops into the Ukraine or Belarus it will trigger a far wider war and invite a strong response from Russia and likely pull in China as an arms supplier - at a minimum and sanctions and trade be damned. There would be no way for the West to block military shipments from China to Russia out without active military action on Russia and China because they share a border. If that happens then WW3 is around the corner and the West has its pants down due to its atrophied industrial base.
Don’t try to make mountains out of molehills, the last thing Russia needs right now is to attack a strong NATO foe.
Poland is sending a strong signal to Russia that it is ready and Putin’s endless bluffs won’t work against it, something that Putin keeps running up against over and over from NATO.
