Notice Pictures with May and Brits

Three pics have no water glasses

Fourth has pics with water glasses

On the fourth pic, two glasses on each forward table (closest to POTUS), one on other tables. Glasses are on the Right side of the Americans, and on the LEFT for the Brits.

Now see the pics on POTUS Twatter.

All pics have glasses on all tables.

On Table closest to POTUS, two glasses on American side and Israelis side.

BUT

American side all glasses on the LEFT

Israelis glasses on the RIGHT

Why the difference? Is it a sign?
