The PLO undermine diplomatic efforts between Arab nations and Israel by engaging in terrorist activities on Israel targets.
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.
Hence it is recognized as a terrorist outfit by Israel and thus the PLO involved in terrorist movements by targeting Israeli people and this weakened diplomatic efforts between the Arab nations and Israel.
