The polling results reflect the general lack of clarity Americans, on the whole, have when it comes to America’s role in the world. Younger Americans tend to be Democrats and are opposed to the US being the self-appointed world’s policemen, which is almost always a cover for neo-imperialism. Older Americans are more apt to be GOP supporters and view Russia in Cold War terms, but some of them, influenced by Trump’s seeming love affair with Putin and other autocrats, might be pro-Russia, or, at least, oppose US involvement. Didn’t that Ukrainian leader keep his distance from Donnie?
The US, of course, has very little, if any, moral standing when it comes to demanding Russia refrain from invading a sovereign country. We have invaded, or supported invaders more than any other in the post-WWII period (Cuba, Vietnam, Dominican Republic, Grenada, Panama, Iraq, Afghanistan), and subverted others (Iran, Chile). International polling consistently shows the US is considered, by far, the greatest threat to world peace. Moreover, we have never disavowed the Monroe Doctrine, which led us to invade our southern neighbors countless times under the guise of defending our national interests.
Our non-existent moral standing doesn’t mean our general stance in this instance might not be appropriate. Every broken clock tells the correct time twice a day.
Unfortunately, while US opinion is not in favor of getting militarily involved in the Russia-Ukraine conflict, US mass media, including allegedly liberal media, such as CNN, never abandon the Cold War script. CNN, for example, has a roster of retired military brass and intelligence officers. They always seem to be favorable to US action. I confess to not watching Fox coverage. I wonder if it might be more balanced because of the division between Cold War sentimentalists vs. Putin admirers among their viewers. Carlson apparently reflects that Trumpist outlook. He’s a huge fan of right-wing autocrats like Orban in Hungary.
Then there is, of course, the commercial value to news media of military conflict. Ratings soar and ad rates do too.
One thing we can be pretty sure of based on history. Even if Americans, when polled, seem to have no appetite for war, if the US gets involved, public opinion shifts into rooting for the home team mode. Sometimes, if the war is over in a few days, as in the case of Grenada and Panama, public support remains high. But if a war drags on that changes and it becomes a political liability. Biden’s popularity is very low now, primarily for reasons beyond his control. There must be some temptation to do something to get a boost. Tough sanctions are one thing, but he might feel pressure to go beyond that.
