Answer:
The PLO undermine diplomatic efforts between Arab nations and Israel by engaging in terrorist activities on Israel targets.
Step-by-step explanation:
- PLO stands for Palestine Liberation Organization which was established in 1964 and it is largely determined for the liberation of Palestine with the cooperation of armed forces and their main objectives are Israeli citizens. They continuously point to target them and enhanced the single true face or the supporter of the Palestine people.
