Why did communism in the Soviet Union collapse in the late 1980s?

Consider:
•Political factors: What did leaders in the Soviet Union, the United States, and Europe do to further the fall of communism?
•Military factors: What effect did military policies and actions in the United States and in the Soviet Union have?
•Economic factors: What effect did the economic situation in the Soviet Union have?
•Social/cultural factors: What was the attitude of the people of the Soviet bloc countries? What impact did glasnost have? What was the impact of dissidents?

what are local authorities doing to fix the problem

explanation:

after a more than a decade and a half of combating al qaeda (aq) in afghanistan and pakistan,

the united states faces a diverse array of threats from al qaeda affiliates in the middle east and

africa. while senior al qaeda figures reportedly remain based in pakistan, the network includes

a number of affiliates across the middle east and africa including al qaeda in the arabian

peninsula (aqap), al qaeda in the islamic maghreb (aqim), and al shabaab. al qaeda also

retains a small but possibly growing presence in afghanistan. u.s. officials have stated that al

qaeda still maintains a foothold in syria through its ties to hay’at tahrir al sham (formerly

known as the nusra front), though the exact nature of that relationship may be evolving. this

report examines the threat posed by al qaeda affiliates in the middle east and africa as described

by u.s. officials and outside observers, as well as the u.s. approach to date in responding to these

threats. this was all i could find hope this : )
