Now it makes sense.
The US dissuaded (=bullied) several countries, through Rubio & US embassies, to NOT participate in the funeral ceremony of Iran’s leader.
13 countries caved in.
3 Eastern-EU, 5 African, 2 Persian Gulf, and 2 East Asian countries withdrew from participating in the funeral.
This might explain why South Africa, Maldives, and perhaps Algeria didn’t attend. They feared it would worsen their relationship with the US.
