Answer:
The main importance is that the brain behind the Al-Qaeda was gone and as their founding chief was killed, it sent a message to all the Al-qaeda members and other terror organizations that no one is untouchable or impenetrable.
Moreover, Osama Bin laden's death showed several different angles on international terrorism.
Explanation:
Osama bin laden was among the founding forces of Al-qaeda, the terror group that made the deadliest attack on US soil since the pearl harbour.
However, his death means several things.
One is that the Al-qaeda lost one of its most important strategic minds.
Second is that this will be a major demoralizing factor to its members.
Third is that the capture or the death of bin laden was a much anticipated fact in the west. The death of bin laden provides a new hope to the America's war on islamic terrorism.
Third is that, as bin laden is replaced, a new era of international terrorism may begin as the Al-qaeda as an organization have not been defeated militarily or politically yet.
And the NATO efforts to uproot the terror group in middle east and Africa have not been successful yet.
