The present government was elected by the Ukrainian people, not installed by the CIA.
The hostility among the Ukrainians traces back to centuries of Russian domination. It is not something manufactured by the US government.
The language law was no more onerous than that of Quebec. And no, the Russian language was not banned.
Ukraine was never a threat to Russia, and Putin knows it.
Finally, Ukraine did abide by the Minsk Accords by passing the law granting autonomy to Donbas and was preparing to hold the required referenda. It was Russia who violated the accords by not withdrawing its forces, not handing over the border to Ukrainian control, and by blocking the referenda that Ukraine was planning.
Enough with your Russian propaganda.
If Ukraine had recognized that and let those areas go, there would have been no war.
