That US empire more than most.

If the US hadn't gone and done the bidding of United Fruit by reinstating their (neo-)colonialist grip over Guatemala via a coup, would one of the the most famous men who described the what, how, where, when and why of taking on US imperialism - not to mention inspiration - ... would Che have even become a revolutionary?

Debatable.

As for wondering what is coming down the line now... well, where to start.

The US is currently at war in bloody wars in Afghanistan and Iraq, where bombing civilians, women and children have been a motif.
Threatening war against Iran.
Heavily posturing against and provoking Russia. (Issues with Ukraine, Poland, Georgia, The Baltic States, the rest of central asia, oil, etc)
Props up economically, supplies militarily and protects Israel diplomatically.
Still has massive numbers of troops deployed in South Korea and Japan, despite massive protests.
Has recently had a coup succeed only to fail within days in Venezuela.
Is meddling in the politics of Bolivia to try and provoke secession by - surprise, surprise - the oil rich elements of the country.
Colombia. Props up economically, protects diplomatically, supplies militarily and praises internationally what is known to be a Failed State. It isn't in the US-sponsored top 10 anymore, but really...

The list goes on.

A coup sparked Che.
Previous Afghani and Saudi adventures sparked Bin Laden.

Iraq is a nightmare, it could easily result in attacks on "The Homeland" down the line. Certain people have been only too happy to recruit Jesus into their war, hence, down the line, potential blowback in the Holy name of Jesus.
