I respectfully disagree. The Left are not smarter but the opposite. They are more crude and corrupt than what Americans have become used to. It's like being attacked by 3rd world hordes. It's like mouth breathing illegal aliens armed with leaf blowers can invade the U.S. and breed themselves into a majority.
I respectfully suggest that you are confusing the pawns with the hand that moves them, when it suits the hand.
You are possibly took focused on the means and tools that they use to get their ends instead of what the long term end power play actually is.
For ease of not going too far down a rabbit hole, let's stick with a well known proven entity that admits to doing all kinds of things... Soros.
A well known, proven and admitted financier of left wing or radical political groups including Democrats (when it suits his purpose).
Are you actually more deviously and strategically intelligent than him?
Unless you have to your credit, bringing countries to their knees financially, overthrowing governments and controlling political parties I'm going to say he's a whole lot better at the games of power than you or I will ever be, can you get the most popular presenter on a major news network kicked off in a day or two by making a couple phone calls?
Don't take my word for it, watch the interviews he gives, he's proud of what he does and enjoys it and is happy to flaunt it when given a chance.
Why do you think Soros, Bloomberg and their buddies spent over a decade pouring money into every little judge and administrator election for people that control the vote counting & vote rule making?
Wonder why so many DAs are totally on the Communist side?
Listen to any of the Global Elite do their full interviews, pretty much every single one will eventually get around to saying the same thing. They want to abolish nations and national sovereignty and national identities and replace it with a one world united order, run of course by the Elites.
Why do you think it's pretty much only western countries being forced to allow this "invasion" as you mention... Means to an end.
