Bulletproof train in the 1920's, so they obviously learned their lesson about leaders of countries riding around in open topped cars...<br>oh hello 1963.....,(reply>), I would say that’s it’s more that the US has many enemies and that the President is the Commander of the military but yea there’s always going to be some maniac wanting to kill someone because they disagree with whatever policies they are trying to push.,(reply>), @Filipe Saramago But that's the thing. A US president does not hold the power of the government, not even close. There are 15 other people in line and even then there are hundreds(Senate and House) left to decide even if all are unavailable so that the government doesn't fall apart. It has nothing to do with how democratic it is.,(reply>), @Carbon its rather about having less democratic regimes that concentrate too much power in a single person and/or dont respond well to public will. Historically, the assasinations of presidents and kings come from their own citizens, not foreigners.<br><br>If the system os democratic and does what the public wants theres no incentive to kill political leaders because any replacement would just enact the same policies,(reply>), @Filipe Saramago I think it has more to do with the political power and relevance of any country. Most of the countries with their leaders just walking around are usually small European ones. The president of the US and prime ministers of Canada and the UK etc have personal protection because they are powerful on the world scale and have people that actually want to hurt them.,(reply>), Even nowadays a lot of leaders of countries just walk the streets, maybe enter a store or go to a restaurant like any other person would. Armoured means of transportation are reserved to dictatorships or at least not fully democratic countries like the US
