They both have the same bosses / owners, it is organised and staged. It's probably to do with trade, and someone isn't getting enough profit, or can see a market or takeover possible somewhere if they kiss and make up.
Keep an eye out for who the next pariah country is - Russia and china are both getting a bit pokey, Iran too. But again, they all have the same bosses / owners.
Strike a light.
Trump has too much stake in Russia to make them a pariah. AS far as china, he may have too much financial skin in that game too. Maybe the 'ish hole' countries of Africa though?
We will see what comes of it as for now, its just talk, and there is alot of that which never comes to much.
for now, i will give credit when it comes due, but it sounds like one bully said, "Oh, id love to meet that guy in person" and the other bully said, "Okay." With Trump being the second bully and not the first. Not a HUGE accomplishment, but again, time will tell.
