Trump x Greenland deal signed by September 23?

Analysis

Donald Trump announced Friday that he had struck a deal with Denmark giving Washington what he called "permanent control" over Greenland's security, barring Russia and China from setting up bases on the Arctic island. Within hours, both Denmark and Greenland confirmed they had reached an agreement, though they stressed it would not compromise Greenland's sovereignty, and officials in Copenhagen said all three governments planned to sign it on the sidelines of the UN General Assembly the following week. That timing is what makes this likely rather than certain. The General Assembly's high-level week runs right up against the September 23 deadline, and while the Danish prime minister's office and multiple reports point to a signing "next week," no source specifies whether that falls before or after the cutoff. Parliamentary ratification in Denmark is explicitly a later step, not required for a deal to be signed. The strength of the case rests on political momentum. Three governments have publicly declared they reached terms, described the substance in detail, and each independently signaled intent to formalize it during a fixed diplomatic gathering. That kind of coordinated announcement rarely stalls at the signature stage once leaders have already claimed victory in public. The one thing to watch is the actual calendar slot: if the signing is scheduled for the tail end of UN week, after the 23rd, or if Denmark's sovereignty concerns force last-minute textual changes, the timeline could easily slip past the deadline.
