Dear Friend, What you have expressed is absolutely right. But that's the 'BEST CASE SCENARIO'. Unfortunately the world and more specifically we human beings have evolved in such a screwed up way that we always live in the 'WORST CASE SCENARIO'. Maintaining an army is a basic necessity in this scenario. For U and me to be blogging from some airconditioned office in some corner of a nation needs these courageous souls to watch our borders.
