No. It is not the case that most civilians walk around armed in the United States. Especially in Washington which has stringent gun laws.Ancientnot saying theres no chance of assassination but America is the country where most civilians walk around armed so the probability for assasination is much higher in USA and the political hate for each other is very high. Many US presidents have been assasinated or shot.
The fact is that the Iranian leadership is far more free to walk their own streets without fear of their own people, than the US administration would ever be.
