There is less anti-gun support today than in many times prior. This is media driven support, giving the public the perception that the nation desires restrictions. The media controls a lot of perception, and that causes americans to believe most Americans are feeling one way, even if most feel another.
Anti-gun sentiment though is nothing new, and it predates guns. A large percentage of rulers have always wanted only those men under thier direct control armed with effective arms. It adds job security. If only your soldiers, the king's men, Knights, Samuria, etc have effective arms then you can always control millions of people with only thousands of troops.
If on the other hand everyone has similarly effective arms, it is a lot more challenging, and forcing the population to do things is more difficult.
Bullying a population is hard if they are as well armed as the men at your disposal.
Having a population with effective arms dispersed amongst it decentrilizes power. Disarming the population and only having the 'professionals' armed helps to centralize power with those who control the people with arms.
The exception to that desire has typically been when they feared conquest by a foreign force in the immediate future, at which point they sometimes embraced short term widespread ownership of arms.
In more modern times for example when Britian borrowed lot of firearms to arm the population when the Nazi invasion was a real possibility. Guns they subsequently dumped into the sea when that threat was over.
If you gather the leaders of most of the world and asked them most would support arms restrictions for the populations, which increases the power thier own forces that remain armed wield. That is also why you see such support for reducing Small Arms and Light Weapons in the UN.
The population armed is a desire of the people, not a desire of the government.
If various leaders (and not just the political ones) can convince the people to desire being disarmed themselves, that is the ultimate success. For they know they will always wield armed men, and those armed men can accomplish a lot more with less effort and resources if they are some of the only armed men. They can implement any policy, and enforce any law, edict, etc with or without the support of the people, with minimal risk to themselves and minimal loss of thier own armed men while utilizing far fewer resources.
