I have read that they are really keeping the numbers to only current heads of state. They are not allowing helicopters to fly dignitaries in, they are asking everyone not to charter jets, but to fly commercial, they are using busses to get them all to the service instead of letting them have their own cars with chauffeurs.
Refreshing to get facts.
I read the same. The media want to make it look like a slight to Trump. In reality, the number of people simply must be limited for the funeral. As much as I despise Biden, he currently holds the office of POTUS. If the Royals had invited Trump, too, they would’ve been slighting the other former presidents. They made the right decision.
