I learned this from lots and lots of research I did years ago. It was back when Obama was president, and the mainstream media were making zero sense. It was also back when Google wasn't censoring and curating their search results nearly as much, so you could still find relevant search results for verboten info. So, I began to do my own research, on numerous subjects.

With regard to the Syrian civil war and the formation of ISIS, I found numerous (often on obscure low profile websites and news agencies willing to post this info) articles written by former intelligence and military people (who disagreed with what we were doing over there), honest journalists (most of them foreign), and others who were detailing what was actually happening in Syria. I was posting all of this on Facebook, back when that was still possible. I deleted all of my Facebook posts when their censorship became apparent and cleaned out my profile. You can probably still find all of this info if you do a bit of digging yourself, with specific search querries on every claim I'm making here, but you'll have to use Yandex. Be ready for doing a lot of reading and be able to put the pieces together, because most of the articles I came across were rather specialized on one specific topic. There wasn't one article that laid it all out and made all the connections, at least not one that I found.

Here are the things I found, that are specific enough you can search for:

There were some Middle Eastern journalists (don't remember their nationality) who found Turkey aiding and abetting ISIS militants. There were numerous first hand accounts from Syria disproving the Obama administration, NATO, and the mainstream media, who were all lying about Assad using chemical weapons against his own people. The first hand accounts said it was either the rebels (before ISIS was formed) using the chemical weapons, or aftermath of conventional weapons made to look like chemical weapons by the mainstream media, or faked entirely by the mainstream media. They (the Obama admin and NATO) used this lie to fund, train, and arm the Syrian "rebels". There were even mainstream media articles detailing/bragging about this, and you might still be able to find them. It was those "rebels" that eventually turned into ISIS. There were also several reports of ISIS being armed with weapons paid for by NATO, using the CIA, and funneling them to ISIS through Turkey. Mossad was also clearly involved. There's also tons of pictures of ISIS with numerous mint condition Toyota trucks. There was also the fact that ISIS, for some weird reason, had incredibly high budget media personnel and equipment, enabling them to put out really high quality execution and propaganda media, which again is really weird, considering no terrorist organization before or since has come anywhere close to that level of media production (like it was being produced by a big budget Hollywood studio with millions of dollars of funding). ISIS claimed to be Muslim extremists, but they weirdly never attacked Israel or jews. They predominantly targeted Christian and non Muslim minorities in Syria (this is a common tactic for anti Christian jews and zionists historically, especially in the Middle East as zionists are actively destablizing surrounding countries to enact the Greater Israel plan). The one time ISIS attacked Israel, they publically apologized. The only motives that made sense for the West to create ISIS and screw over Syria was 4 fold: so a Middle Eastern country (can't remember which one) could run an oil and gas pipeline through Syria and into Europe, so the Rothschilds could gain access to Syria's oil and gas (like I said, they slant drilled from northern Israel into southern Syria's oil to steal it during the civil war), to put pressure on Russia (they wanted to start a proxy war with Russia even back then), and to further their Greater Israel plan. Syria was/is Russia's only ally in the region, which is why Assad denied the oil and gas pipeline through his country, as it would compete with Russia's oil and gas exports into Europe (remember how the U.S. blew up one of Russia's undersea pipelines into Europe recently). Thus, the Obama admin and NATO created ISIS and lied about Assad to try and oust him. They did the exact same thing in Libya to Gaddafi, and with the Muslim Brotherhood in Egypt during the "Arab Spring". In fact, there's really good info that the 2012 attack on the U.S. consulate in Benghazi, Libya (where ambassador Stevens and a few CIA contractors died), was because the Libyan rebels (which we similarly armed to oust Gaddafi, because he dared to go against the international bankers and try to implement a gold standard in his country) were getting pissed that we were taking their weapons away and funneling them to the Syrian rebels, flying them into Turkey and smuggling them across the border. That was ambassador Stevens' job there, to help funnel those weapons. It's also why Obama amd Hillary tried so desperately to sweep Benghazi under the rug. It's also been suggested they wanted Stevens to be killed, so he would never have a chance to talk about what he did (as a middle man), as we had military assets that could've reached them in time, and were in the air already heading toward Benghazi, but were ordered to be turned around. Even though I'm no longer a Trump supporter, he clearly put a damper on whatever plans these assholes had in Syria, because immediately after Trump got into office, ISIS disappeared, virtually overnight, like they had all their funding, personal, and support taken away. Muslim extremists don't act that way, which means the entire organization was being controlled, from top to bottom, by the CIA and Mossad.

This is most of what I could remember off the top of my head. This is already quite long, and if you haven't heard of this stuff, you have s lot of research to do. But, again, use Yandex. All Western search engines are unreliable for finding this stuff nowadays. For context, keep in mind that the Syrian civil war happened right after Libya, which happened right after the Muslim Brotherhood coup in Egypt, which happened right after Iraq, and during the latter part of the deadliest part of the U.S. occupation of Afghanistan. It was called the "Arab Spring", which was complete bullshit meant to give cover to Western meddling in the Middle East. Look up articles for how the Egyptians felt after Obama supported the Muslim Brotherhood coup in Egypt. It was crap like this that made people suspect that Obama was secretly a Muslim. Although, looking back at it now, it's obvious that most of those "Muslim" extremist organizations and terrorists were being run, in part or entirely, by the U.S. and Israel.

Here is Assange, on RT, explaining that ISIS is funded by Saudi's and Qatar.
