Protest. Create awareness. Because, you now, unlike the Chinese or Russians, Americans have the freedom to do so without getting vanished in re-education camps and gulags.
Fair enough, China and Russia managed to compete with the US in the last couple of years. Enjoy.
Do the guy also love US terrorism and foreign interference? Because that's what people probably take most offence with. There is not a single additional nation on this planet that has couped to many democratically elected governments and replaced them with corrupt authoritarians that are more than willing to oppress and torture their people and cause civil wars and sell out their nation's interest to US interests in exchange for power. The US is sole world leader in evil and hase been for over a hundred years, only briefly eclipsed by individuals like Stalin, Mao, Hitler, Kissinger.
Because as someone who is "deeply critical" of US his government and military, he really seems like jeans and jack o'lanterns have any weight when people call the globally most hated nation on earth a barbaric terrorist shithole.
And let's not even start counting warcrimes or threats of acts of war towards their "allies".
Fun fact: ask people to name three governments the US has couped. See what happens. Just three.
