Its all biyadei shamayim (ok, i just learned how to do that, so i am trying it all out…)
It is probably all mass hysteria and that is what terrorists aim to do: scare us all so that we cannot live our normal lives. Just be on the lookout for anything suspicious, and daven to Hashem. I would be extra cautious around arabs while the war is going on because they are pretty upset at Israel and Jews right now (more then their normal fanatical hatred…) so dont do anything to get someone angry… but act out your normal life!
