Look at this:
http://news.bbc.co.uk/2/hi/africa/7307521.stmAfter repeating that al-Shabab would not stop fighting or engage in reconciliation talks until Ethiopian troops withdrew from Somalia, he said: "We will continue to attack peacekeepers in Somalia, regardless of their nationality."
al-Shabab thinks they can humilliated Ethiopia,Aweys thinks he can insult Western countries without problem.The only language that islamists and somalis understand is violence and war.
Only two countries can deal with the somali problem:URSS and Cuba,they know how to deal with somalis.
The somalis only feared these 2 countries.
