Whenever somebody says that everybody of a certain large group (such as all nationals of a country) wants something, they're pretty much always shameless lying since they don't actually know that and they KNOW that they don't know that.

To be able to say that truthfully they would need to have done some kind of survey (which is pretty much never the case: they just say this lie as a way to convince people that everybody else wants something so they should too) and there is pretty much no subject were everybody of a large enough group agrees (even for seemingly universal desires, like in "Americans want to live", somebody somewhere disagrees, otherwise there would be no suicides).

It's a pretty big red flag when a politician lies like that as part of their way to convince people to agree with something, even one which one might at first thing is "on my side".
