It is too early for Trump to brag about achievements

Aboard Air Force One on his way back to Washington after meeting with Democratic People's Republic of Korea leader Kim Jong-un in Singapore on June 12, US President Donald Trump thanked Kim on Twitter for "taking the first bold step toward a bright future for his people".

The Trump-Kim summit is historic, not least because it brought together the incumbent leaders of the United States and the DPRK for the first time.

But the joint statement that Kim and Trump signed is vaguely worded. Trump hailed it as a "comprehensive document", though, saying the DPRK would "work towards the complete denuclearization of the Korean Peninsula" while committing to "lasting and stable peace". Also, the two sides agreed to establish new relations "in accordance with the desire of the peoples of the two countries for peace and prosperity", with the US agreeing to provide "security guarantees" to Kim.
