The backdrops to the Putin/Trump meeting are the aspirations of Israel and the neoconservatives. It is these aspirations that drive US foreign policy.
What is Syria about? Why is Washington so focused on overthrowing the elected president of Syria? What explains the sudden 21st century appearance of "the Muslim threat"? How is Washington's preoccupation with "the Muslim threat" consistent with Washington's wars against Saddam Hussein, Gaddafi, and Assad, leaders who suppressed jihadism? What explains the sudden appearance of "the Russian threat" which has been hyped into dangerous Russophobia without any basis in fact?
The Muslim threat, the Russian threat, and the lies used to destroy Iraq, Libya, and parts of Syria are all orchestrations to serve Israeli and neoconservative aspirations.
The Israel Lobby in the United States, perhaps most strongly represented in Commentary, The Weekly Standard and The New York Times, used the September 11, 2001 attacks on the World Trade Center and Pentagon to urge US President George W. Bush to begin "a determined effort to remove Saddam Hussein from Power in Iraq." See here also.
Saddam Hussein was a secular leader whose job was to sit on the animosities of the Sunni and Shia and maintain a non-violent political stability in Iraq. He, Assad, and Gaddafi suppressed the extremism that leads to jihadism. Saddam had nothing whatsoever to do with 9/11, and under his rule Iraq constituted a ZERO threat to the US. He had been a faithful vassal and attacked Iran for Washington, which had hopes of using Iraq to overthrow the Iranian government.
Removing secular leaders is what unleashes jihadism. Washington unleashed Muslim terrorism by regime change that murdered secular leaders and left countries in chaos.
Fomenting chaos in Iraq was the beginning for spreading chaos into Syria and then Iran. Syria and Iran support Hezbollah, the militia in southern Lebanon that has twice driven out the Israeli Army sent in to occupy southern Lebanon so that Israel could appropriate the water resources.
The neoconservatives' wars against the Middle East serve to remove the governments that provide military and financial support to Hezbollah. By spreading jihadism closer to the Russian Federation, these wars coincide perfectly with the US neoconservative policy of US World Hegemony. As expressed by Paul Wolfowitz, US Undersecretary of Defense for Policy:
"Our first objective is to prevent the re-emergence of a new rival, either on the territory of the former Soviet Union or elsewhere, that poses a threat on the order of that posed formerly by the Soviet Union. This is a dominant consideration underlying the new regional defense strategy and requires that we endeavor to prevent any hostile power from dominating a region whose resources would, under consolidated control, be sufficient to generate global power."
Israel wants Syria and Iran to join Iraq and Libya in American-induced chaos so that Israel can steal the water in southern Lebanon. If Syria and Iran are in chaos like Iraq and Libya, Hezbollah will not have the military and financial support to withstand the Israeli military.
The neoconservatives have broader aims than Israel's. The neoconservatives want Syria and Iran in jihadist turmoil so that the neoconservatives can send jihadism into the Russian Federation and into China. China has a Muslim province that borders Kazakhstan. By causing internal problems for Russia and China, the neoconservatives can reduce Russia and China's abilities to hinder US unilateralism.
That is what Syria is about. It is not about anything else.
The "Muslim threat" appeared suddenly with the 9/11 attack on the WTC and Pentagon. The attack was instantly blamed on Muslims. Although the US government maintained that it had no idea that such an attack was in the works, the US government knew instantly who did it. Quite clearly, it is impossible to know instantly who did an attack about which the government had no idea. In what has become the hallmark of every "terrorist attack," IDs left at the scene conveniently identified the "terrorists."
There are now 3,000 architects and engineers who put their reputation on the line by challenging the official story of the collapse of the WTC buildings. According to all known science, the official explanation of the destruction of the three highrise WTC buildings is strictly impossible. There is endless evidence online provided not by ignorant presstitutes, conspiracy theorists, and lying politicians, but by real experts. Just go to the Architects & Engineers for 9/11 Truth website, to the Firefighters and First responders for 9/11 Truth website, to the Pilots for 9/11 Truth website.
Research what some foreign government officials have to say about the absurd story told by the US government. That any percentage of the US population believes the obvious false official 9/11 story is proof of the total failure of education in America. Much of the population is incapable of thought. People simply accept whatever the government tells them regardless of the absurdity of the explanation.
