If there is need to be at war, especially for ideological reasons, you have to fight the war.
I don't mean to carry arms and weapons, I mean disagreements that are aimed at proving a point in the intesrest of national development.
As a matter of fact, sometimes you have to fight the war in order to be at peace.
So, depending on why we have to fight a war, there is nothing wrong with fighting a war.
HAPPY VALENTINE'S DAY!!!
