No. I'm not a puppet for politics and rich people trying to fortify geopolitic positions. Anyone who goes thinking they are fighting for "their country" or "freedom" is just a manipulated puppet being used as cannon fodder.
It's OK to love your country (I do love mine), but it's not worth to lose the life over it. A country is just a border that was the result of several quasi-random historical events.
If losing the war would make you lose your life or would bring great suffering to you or your family, then it can be deemed reasonable. So basically, in a worldwide scenario, nothing since WW2.
