China against the USA - another idea.
While the new version of Red Dawn is interesting enough I think a better possibility is a movie that was certainly little heard of in Australia (and maybe so in other countries).
It's a low budget movie (funded on IndieGoGo) called "Dragon Day" and uses the premise that the US is unable/unwilling to repay its debt to China and then... "if you borrow money to buy a house and you can't repay the loan, the bank takes possession of the house"... in this case, China is coming to take possession of the USA.
I'll put a spoiler at the bottom so I don't reveal anything more for those who want to watch it without knowing what happens but take note that the trailer also reveals part of the story plot.

-- SPOILER - mouse over to highlight --
China has been supplying all the IC chips for electronics in common use, they have installed a programme on the chips to allow them to control or sabotage the device the chip is installed in. They activate the programme and cause governmental, defence and societal breakdown and then just sort of walk on in and take over by only offering relief supplies to those who join them.
