You're right again. The USA should not be called 'America'. You made me remember South American friends who used to find that really galling.
Don't forget we have a duopoly too and when it comes to 'empire' our govt, no matter blue or red, also usually follows what we are told to do. We have been involved in all large-scale US-related wars last century and this century. We don't exactly look like a beacon of independence or decency ourselves. We are still selling F-35 parts to Israel which are used to kill civilians. We may be involved in facilitating weapons for Sudan where a horrific genocide is also happening.
Does it suck to be a decent Australian? It might make us feel ashamed or frustrated about our situation but I'd say no, it doesn't 'suck' because we love our country. The same can be said for decent Americans. Their situation has become extreme but if you look at most capitalist nations the problems are similar because we are tied into the same exploitative scrum.
