As war between the West and Islamic State escalates, little is known of IS leader Abu Bakr Al-Baghdadi. Is destroying Al-Baghdadi the key to defeating terror? This report explores the ISIS reign of terror in Syria. Subscribe to journeyman for daily uploads: http://www.youtube.com/subscription_center?add_user=journeymanpictures One Muslim Community s Fight Against Extremism in Belgium - Trailer https://www.youtube.com/watch?v=QbxzCn1QtBc The Hidden War Between The Kurds And Turkey https://www.youtube.com/watch?v=krxv6iVaR7o The Children Brainwashed To Become Jihadis https://www.youtube.com/watch?v=kAYHAovJy84 "Al-Baghdadi has only appeared in public once, and after that never again", describes Hani. Like so many Syrians, Hani fled from the brutality of the Islamic State after they captured his hometown of Raqqa. It is not only in Raqqa that the lives of citizens are in danger. While Sinjar is one of the first major cities that ISIS has had to give up, after their retreat the horrendous consequences of their reign of terror became clear. Mass open graves filled with bodies revealed the remains of anyone who did not share their beliefs. Captured by US forces in Iraq in 2004 and detained at Camp Bucca, Baghdadi has gone on to build a powerful and remorseless caliphate intent on world Jihad. "Al-Baghdadi wants to be portrayed as the religious leader of this new nation. But he wants to be invisible. This only increases his appeal", explains an expert. In response to their growing strength, Western powers have increased military retaliation in Syria, but this war cannot be fought with weapons alone; it is far more complex. As one expert describes, "you can t bomb an ideology...if you try to bomb an ideology you will only reinforce it".

Face masks don t make you invincible. Support Vox by joining the Video Lab at http://vox.com/join or making a one-time contribution: http://vox.com/contribute The fight against coronavirus is global. But the guidelines on whether you should wear a face mask as part of that fight are often completely different from place to place. That means that, for a lot of people, whether you wear a face mask when you leave the house is basically up to you. Here’s where almost every expert agrees: If you have Covid-19, and you leave the house, you should wear a mask. Masks help keep sick people from spreading their germs. Most of the uncertainty around mask use is related to a totally separate question: Whether masks can protect healthy people from getting Covid-19. The truth is that no mask can actually guarantee that you won’t get sick; experts say one of the most dangerous assumptions about face masks is that they basically make you invincible. Masks have to be used correctly to offer any protection at all, and they’re most effective if used alongside other preventative measures like hand-washing and social distancing. But experts also say that the question of whether healthy people should wear masks is a lot easier to answer when you consider one of Covid-19’s most dangerous characteristics: Because of the disease’s long incubation period, and the high occurrence of infected people who never feel symptoms at all, it’s almost impossible to be completely sure that you don’t already have it. And that means the safest course of action is ultimately for everyone to behave like a sick person; in other words, to wear a mask.

How did the Ottomans overcome an internal crisis? History of the Ottoman Empire (1400 - 1500) " The start of the 15th century in the Ottoman Empire marked the final years of Bayezid I’s reign as Sultan. In 1400, major tensions began to rise between the Ottoman leader and a Turko-Mongol warlord by the name of Timur. This once cold-war reached a heated climax in 1402 at the Battle of Ankara. While on his way back through Anatolia to confront the threat of his powerful rival, Bayezid was caught off guard by Timur and his troops as they besieged the city of Ankara, withholding the only source of water for the Ottoman troops and forcing them to engage in battle. By the end of the conflict, Timur’s army prevailed while Bayezid and his sons attempted to make an escape.

Based loosely on Keith Jenkins’ Rethinking History, this video looks at postmodernism effect on the writing of history, and how ideology, methodology and epistemology shape how history is written. I also look at Margaret Appleby, Lynn Hunt and Margaret Jacob’s Telling the Truth About History, which emphasises how the history of America has changed over time. Thomas Kuhn’s paradigms and Michel Foucault’s epistemes make a guest appearance! Then & Now is FAN-FUNDED!

Thailand’s capital city, Bangkok, is unique. This film reveals the best spots: well-known locations, and places off the beaten track. Our report provides a detailed guide to Asia’s most exciting city. For transportation, visitors and local residents alike can choose from motorized rickshaws, taxis, subways, or the sky train. There are also express boats that ply the Chao Phraya River -- plus long-tail boats, and vessels that make their way through the city s khlongs, or canals. This journey of discovery takes us to the places where Bangkok residents go to rest and relax -- like the island of Ko Samet in the Gulf of Thailand. This is the capital s version of Wannsee Lake in Berlin. You can book a river cruise, or visit one of the trendy open-air bars perched atop high-rise buildings. A lot of younger Bangkok residents have taken up a bold challenge in this car-friendly city: they ve switched to bicycles. Many locals enjoy making a bike visit to the village-like central district, near a big bend in the river -- even when the temperature rises above 30-degrees centigrade. On the islands off the coast, there s plenty of sunshine, beautiful beaches, and clear, warm water -- a mix that attracts crowds of Bangkok residents on weekends. _______ Exciting, powerful and informative – DW Documentary is always close to current affairs and international events.
