I think there was more to this than just pointlessness. Say, you want to have a meeting with specific leaders, but you know that bringing them in will get out, and folks may be able to figure out what you're up to based on who you bring in for the meeting.

So, you bring every leader in for a pointless meeting publicly, while then having a secret meeting afterwards with the actual leaders you wanted to talk with.

Who they actually wanted to talk to, i don't know, but my guess it was the leaders stationed in the Middle East, based on all the ships we've been sending to the region, as well as Trump's ultimatum to Hamas, and the recently announced plan to turn Gaza over to Tony Blair. I have a strong feeling Trump is sending American troops in to help Israel take over Gaza entirely.
