Fascism (/ˈfæʃɪzəm/ FASH-iz-əm) is a far-right, authoritarian, ultranationalist political ideology and movement, characterized by a dictatorial leader, centralized autocracy, militarism, forcible suppression of opposition, belief in a natural social hierarchy, subordination of individual interests for the perceived good of the nation or race, and strong regimentation of society and the economy.

As per the wikipedia definition, it does seem the USA has been fascist towards the rest of the world, just not towards its own citizens (overtly) until now…

So if we agree fascism can apply internationally but not domestically (which is not usually how the term is described) then the meme is accurate
