Bolton is a big fan of WW3 but now he has a personal stake in making sure the meeting happens and produces results
On a gestalt basis it seems to me from all the bits and pieces of information and rumor that DJT is attempting "The Deal of the Century!" (an episode or two of his soon to be award winning series on the subject of "The Greatest President.")
Russian cooperation in this is clearly needed. Trump is blessedly lacking in ideological fervor. His Deplorable base is also a bit short on ideology being focused on wages, prices, taxes and other everyday living issues. Their patriotism expresses itself in devotion to the flag and the anthem and a willingness to serve in the armed forces, something increasingly absent in the "resistance."
Trump has a free hand from his base to negotiate peaceful coexistence with Russia, but he nevertheless must successfully deal with the passion of the neocon wing of the Borg (foreign policy establishment). They still swoon at the thought of the ongoing renewal of the Cold War.
John Bolton is an arch-neocon, a neocon's neocon. Trump has sent him to Moscow to arrange an agenda, date and location for a meeting with Vladimir Putin. IMO this is a stroke of genius. What it does is put an enemy of good US-Russia relations in charge of arranging the schedule for discussions to improve US-Russia relations. In LBJ's vulgarism, Bolton is going to be inside the tent peeing out rather than outside peeing in. Having arranged the meeting, he will be personally invested in its success. How sweet that is!
Trumps is IMO trying for a grand ME bargain to be achieved with Russian help:
1. Peace in Syria in the context of abandonment of regime change. Trump the pragmatist recognizes that the R+6 forces have won the civil war and, therefore he wishes to accept the sunk costs of previous American ineptitude in Syria and to walk away. US Embassy Amman has signaled to the FSA rebels in SW Syria that they should not expect the US to defend them. This is a traditional American stab in the back for guerrilla allies but the warning indicates to me that some group in the US Government (probably the CIA) has enough conscience to want to give warning. As soon as that warning was issued the rate of surrenders to the SAA rose.
2. The US has thus made it clear that the SAA and Russian forces in Syria have a free hand in the SW and it seems that Israeli air and missile attacks are unlikely against the SW offensive. This has been insured through a Russian mandate that Hizbullah and IRGC dominated Shia militias stay out of the fight in Deraa and Quneitra Provinces.
3. The Egyptians have been talking to Hamas about their willingness to enter into a hudna (religiously sanctioned truce) with Israel. Hamas has frequently offered this before. Such truces are renewable and are often for 10 years. Kushner's team thinks it has attained Natanyahhu's support for this. The deal would supposedly include; a Gaza-Egyptian industrial zone in the area of Raffa, an airport, a seaport. In return Hamas would be expected to police the truce from their side of the border. People on SST who have deep access in Israel doubt the sincerity of apparent Israeli assent, but there is little doubt I think that DJT considers this part of the Grand Bargain he is attempting to forge.
Nowhere in any of this is anything concerning Iran and I assume that regime change remains the policy. Nor is there anything about Saudi Arabia and the UAE's mercenary manned war in Yemen. Ah, well, pilgrims, everything in its time.
