As an American, and a lifelong Democrat, he is the single most dangerous threat that has happened to this country, and possibly the world, in modern times.
This has been a long term plan by the Republicans who are backed by billionaires to take over the government of our country. Trump is just the face. He's not the brains.
He wants Greenland because it is the eastern gateway to Artic oil, and rare metals, and China and Russia already control routes to this area. China and Russia either have increased or are attempting to increase their overall land mass, i.e., Singapore and Ukraine. Trump wants to become the Dictator of North America like those leaders are dictators of their own massive areas and increasing land mass is in the dictator playbook. If he is successful, these 3 massive dictatorial superpowers will begin to carve up the world.
If he continues, what he is doing could destroy the North Atlantic Treaty and replace the United Nations. It would leave Europe without a major ally and Putin at the gate. It's hard to take him seriously because he is such a clown, but his backers are billionaires and like all billionaires, for them, there is never enough. In case you didn't know or forgot, he loves Putin.
Trump wants to go to war so he can use the US War Powers Act to stay in office past his term. He has an ersatz "Peace Board" supposedly for Gaza that he is, right this moment, currently stumping in Europe. What it will do is create an alternative to NATO. Macron rebuked it, even Israel rebuked it, and the UK, Germany, Sweden, Netherlands, and Canada are not taking part. But Belarus's Lushenko has signed on, and so has Erdogan of Turkey, as have Morocco, and Hungary. What he wants them to sign will gives the power over governing this new organization specifically in Trump's hands for all decisions. Qatar is also included as a signatory along with Argentina and Italy has shown interest.
We should all be afraid, very afraid.
