Not just ISIS: Terror groups worldwide struggles for power

    As ISIS becomes the world most dangerous set of humans, other terror also in the world, also trys to get more tougher.
   These are some snapshots of some of the most significant groups and how they differ from ISIS:

   Al-Shabaab What the name means:
      Al-Shabaab means "The Youth" in Arabic. It's also known by several other names, including the Mujahideen Youth Movement, the Mujahidin Al-Shabaab Movement and the Mujahidin Youth Movement.

  What they want:
      Al-Shabaab wants to turn Somalia into an Islamist state, complete with a strict form of Sharia -- or Islamic law, according to the Council on Foreign Relations. They've even recruited some Americans, including from the Somali-American community in Minnesota. How big of a threat is Al-Shabaab to the United States?
  Who they've recently attacked:
      In late July, Al-Shabaab suicide bombers killed at least 12 people near Mogadishu's international airport. An Al-Shabaab spokesman said the group was targeting the peacekeeping mission UNISOM (United Nations Assistance Mission in Somalia).
       While many of Al-Shabaab's attacks are inside Somalia, two of its most gruesome attacks took place in Kenya.
       Last year, Al-Shabaab gunmen killed nearly 150 people at Kenya's Garissa University College.           And a four-day long bloodbath at Nairobi's Westgate Mall left at least 67 people dead in 2013.
   Al-Shabaab said it had sent the gunmen to the upscale mall in retaliation for Kenya's involvement in an African Union battle against them. Kenya has also been a key U.S. partner in battling Islamist terrorism.

   How they're different from ISIS:
       Al-Shabaab is al Qaeda's proxy in Somalia. So how does al Qaeda differ from ISIS? ISIS is primarily focused on solidifying an Islamic state over swathes of Iraq and Syria. It might inspire "lone wolves" in the United States and Europe, "but it is not directing its resources to attack in these areas," Daniel L. Byman of the Brookings Institution said. "Al Qaeda is weaker and less dynamic than the Islamic State, but the former remains more focused on attacking the United States and its Western allies."
