President of the European Parliament Jerzy Buzek Sunday stated that the attacks of 11 September 2001 in the US "opened an era which symbolically ended on 2 May 2011 with the death of Osama bin Laden in the compound of Abbottabad Pakistan." "Terrorism was not born on 9/11 and it is not over with the death of Osama, but the world has changed in the last decade, and for the better," he said in a statement to mark the 10th anniversary of 9/11. "Over the last 10 years, we have often been confronted with the question of the delicate trade-off between freedom and security. We should never give in to the temptation of sacrificing the former at the altar of the latter," he noted. Buzek opined that the EU's biggest challenge in the fight against terrorism in the next decade will be state and institution building. "Terrorism proliferates in failed states, it in turns affects the neighbouring countries and can destabilise entire regions. We see this in Somalia, in the Sahel region and in Yemen. The situation in Pakistan is also of grave concern. In Pakistan alone between 2003 and 2011 some 37.000 people have been killed in terrorist acts," he said. "This reminds us that those who commit terrorists act do not discriminate. Terrorist attacks kill people all of religions and of none. Al-Qaida has been the greatest threat against the communities it claims to represent," he added.
