This could be a possibility and maybe they think they should be prepared in case a invasion occurs and they should be ready so they can fight them back if needed. Czech maynot trust Russia and are getting weapons and tanks which will help them if any terroist group enters or country and fight them back before it get's out hand and the economy is good over there so can spend this amount I think many countries will have to make sure the defense is good, as there have been rebel groups or terroist ones who want to be supreme and needs to be stopped before they do get to that stage. It will be interesting to see what happens in the coming days and and weeks and hope it works out real well and should make positive changes to happen.
