What doesn't kill you will kill you later

I've often heard people say "bi iyyem el 7areb" then referring to stuff they have been through which made them suffer of course but did it make them stronger?
i think people who lived during a war would naturally be peaceful human beings because of the injustice, the deaths and the tragedies they've gone through
But we should also consider another theory
these people have witnessed so many horrible unjustified things that they would want revenge
I was thinking the other day that world war II has ended only 6O years ago so the memories are still fresh, some of those who have been through this war are still alive and the reasons, ideologies and consequences of this war still exist.
We should wait at least another century for the effects of this war to fade away completely, until the whole generation disappears .
Of course we shouldn't forget what has been done and said but we will always have history books to remind us but i mean in the future the whole pschological consequence of war would have disappeared.
So to explain all the insanities in this world when it comes to politics in the "Western World" i think we can blame it on previous wars
On a more local point of view, i think the huge gap between you and your parents is of course in some part due to technology but it is also a consequence of the last war in lebanon
This is why sometimes you whine about every little thing and they can't stand that because war made them appreciate life and lowered their standards of what happiness could be.
So for those of us who weren't born in the last war but who had to live its consequence (unemployement, bad economy etc...) and who are now living this horrible war and feeling completely powerless ; how will this affect us i wonder?
Because u reassure urself by saying this will make u stronger when actually it could tear u appart in the next few years!
