That’s a false premise. The government in the US does not need popular approval to do things. There isn’t direct voting on any of these actions and pressure on politicians is indirect and very slow for all but extremely egregious actions.

Are you sure about that? Every US history class I've ever taken growing up told me about some form of propaganda usage by the US government prior to some action. WWI, WWII, Cold War, Vietnam War, Iraq War etc.

Propaganda is as much about convincing "the people" as it is convincing the "internal apparatus". Of course, for something like WWI, you have to have propaganda because the effort required is too large -- you can't do WWI or WWII with the apparatus alone.

But it's very important, even for the people "on the inside", to believe that they are fighting for the right cause, to be able to rationalize their actions. If you need something morally fraught to be done (like fight a war), the people doing it, regardless of who they work for on paper, are much more effective if they believe in their hearts that it's the right thing to do. Propaganda isn't really about convincing people do to things, it's about giving them the emotional toolkit to justify doing things with purpose and pride.

There wasn’t propaganda before WW2. Japan hit Pearl Harbor and the US was at war by the time people were just hearing about it.

The only propaganda before Vietnam was the general red scare. Nothing specifically prepping people to go to war in Vietnam. Once there, propaganda definitely ramped up to keep people happy with a draft.

The point is that no approval is needed to do stuff. There is often propaganda later to help justify it, but that doesn’t limit the speed or capability of what can be done.
