Seems that she has strong charisma to her people. But aside from that, I believe she also did a lot to her countrymen, that's why people love her. Let's see how she will handle the aftermath of the pandemic in her country. Can they easily recover ahead of other first world countries?
Talking about recovery.
They have overcome the pandemic. While the rest of the world is still in recovery, they're now living their lives normally. There's no need for them to recover, they are in the first phase and went their lives back and their entire economy normal.
First world or any type, what matters is they are not the same as us who are still dealing with the pandemic. They can go everywhere and their economy is just continuing while us, we're into lock downs and have travel restrictions.
