Have you seen how many nukes Russia has got? Although I don't buy into the conspiracy theories, you have to take Russian aggression seriously. Ask Ukraine, Georgia, Syria, Libya, Belarus etc and they will tell you, you don't need a large economy to be the bully on the block.
Actually it's around 320 million and these are preventable deaths. If you were talking about Covid I would agree statistically it is not worth worrying about but why only in America do you have so many school shootings.
