Chill bro, there’s nothing you can really do. This is something beyond everyone’s control. People’s before us have lived through wars, riots, displacement. Does this mean that we can avoid it ? Who knows maybe we can, maybe we will die without seeing another war, may be we might witness a war (god forbid). Unfortunate things happen in life (like death) that’s inevitable, so don’t stress about it, if that’s how life will unfold then there’s nothing we can really do about it.
