If you are the one being attacked and invaded, you have no choice. Either you submit to the invaders or you fight them. So, for the one being attacked, it is necessary. If you are asking if THIS war is necessary, now we are in an entirely different area. Now we are asking if it is necessary to start a war.I can only say that I joined the military to repel invaders, not be an invader.Up until this moment, I could never have imagined myself doing what I did nearly four years ago. While I was already past mandatory retirement and being forced out one minute and being told I couldn't retire because they might need me for what was then the oncomming war. I made up their minds for them. I submitted my retirement papers and forced it down their throats because i do not believe in the current policy.
