Why was Kim’s letter for Trump so big?

SEOUL, South Korea — North Korean leader Kim Jong Un is known for pushing the envelope with threats and bluster as he seeks to leverage his nuclear weapons program into security and economic benefits for his country. But lately he’s gained notoriety for his envelopes alone.

President Donald Trump on Friday declared that his on-and-off summit with Kim was back on again.

The announcement came after Trump hosted a senior North Korean envoy at the White House and he delivered a personal letter from Kim that was inside a white envelope nearly as large as a folded newspaper.

Trump has not yet revealed what was written in the letter, but he sure seemed happy to get it.

Did Kim, a third-generation heredity leader, think Trump would share his love for lavish gestures and things grandiose? After spending months trading insults and war threats with him, has Kim learned that the way to influence Trump is to appeal to his ego — something South Korean President Moon Jae-in seemed to try in April when he openly vouched for Trump as a candidate for the Nobel Peace Prize?

No one outside North Korea likely knows the real reason for the letter’s size. It could just be that’s how Kim likes it.
