Violence has declined in northern ireland because terrorist organizations

have agreed to negotiate.

Explanation:

Terrorism in Northern Ireland has been a concern since the late 1960s. Although it cannot be considered eradicated yet, it is not a significant cause of concern since the the signing of the Good Friday Agreement of 1998. Violence has significantly decreased because terrorist organizations have agreed to negotiate. The terrorism in this region is mainly political and nationalistic in character, often stemming from the debate surrounding the constitutional status of Northern Ireland and the possibility of a united Ireland.

the main reason the us senate rejected the treaty of versailles was because "european nations wanted to punish germany"
