The full question is: "How does the US persuade Denmark to part with Greenland when the EU Parliament, Klaus Schwab, the Communist Party International, George Soros, and the CCP are screaming at Denmark's leaders to never, ever, ever cooperate with Donald Trump or the USA - in anything?
Talk about Greenland and the Panama Canal is not really a suggestion to foreign leaders, who don't have the agency to agree, anyway. It's a warning to the Dr. Evils of the world that in the event of a serious conflict the USA intends to seize those areas. The real fireworks will come when China tries to apply the same logic to the Straits of Malacca.
Straight of Malacca?
How about the Straight of Taiwan, Luzon Straight and the South China Sea?
