Everyone sending messages, but what do they mean?

The US dropped a MOAB, which stands for Massive Ordnance Air Blast, bomb on hill in Nangarhar Province in Afghanistan, killing over 90 ISIS fighters, who were hiding inside fortified caves. The MOAB, also known as GBU-43/B, is so huge that it has to be carried on a cargo plane, which are easy to shoot down, and its blast radius is around 1 mile, so the risk of collateral damage is enormous. That is why it has never been used in combat. Apparently, this was designed to send a message. But what message and to whom? According to some it was a message to North Korea and Iran not to mess around with nuclear weapons. To reinforce its message to North Korea the US started a surprise exercise at its airbase in Japan. Not to be outdone North Korea started to send a series of strange messages over short wave radio, such as 'No.69 on page 823, No.92 on page 467 and No.100 on page 957'. "If your opponent is of choleric temper, irritate him," Sun Tzu. North Korea held a massive parade to celebrate the 105th anniversary of Kim Il-Sung, the grandfather of present leader, Kim Jong-Un, showing its missiles, and followed it up with a missile test, which exploded within seconds of the launch. Was it deliberate? We can also create a big bang but we will not show you our real capability. In February, North Korea sent another message by assassinating Kim Jong Nam, the half brother of Kim Jong-Un, in Kuala Lumpur airport, using the banned nerve agent, VX. This may have been to show the world that it had the capability of producing deadly chemicals and anyone thinking of attacking the country should think twice. Or it could be a message to China that its support was welcome but it should not try to decide policy. Earlier this month the US fired 59 Tomahawk cruise missiles at an airbase in Syria which was blamed for an alleged sarin attack on a village in the north. Although why Assad would use a chemical weapon when he is winning the war has not been explained. Russia and Iran were not amused and promised reprisals if there are any further attacks. There was no ambiguity about this message. In response to MOAB Russia boasts of having a thermobaric weapon, which it calls the 'father of all bombs'. It is one thing to bomb ISIS, which has no air force, but quite another to bomb North Korea or Iran, which is probably busy making its own nuclear warhead at its fortified underground facility in Fordow. Mahmoud Ahmadinejad, a hardliner, has declared that he will run again for president. This maybe a message that he would like to have dinner at Mar-a-Lago, just like Xi Jinping had or it maybe a message to liberals that he is still there. So many messages are terribly confusing. As Donald Trump said,"I don't know if it this sends a message; it doesn't make any difference if it does or does not." Scary.
