Iraq- Suffered due to Saddam's policy of aggression first allied with GCC attacking Iran and then turning the guns on GCC itself. He underestimated Iran's capabilities to defend itself against an Iraqi invasion. He then underestimated the desire of United States to defend its protectorate colonies of Kuwait and Saudi Arabia. In the process Iraq a relatively progressive country in 1970's, suffered enormously.
Libya- Fell in a color revolution promoted through application of new technologies such as social media and social engineering. The goal of the color revolution was/is to destabilize the Muslim lands and re-map them for this century. The chief mistake of Qaddafi was his giving up his rhetoric and his entire scientific structure of his nuclear program (all the nuclear program of Libya was literally packed in crates and transported to United States). The rhetoric and the mere danger of a country going nuclear matter in geostrategic balance. Once you lose the rhetoric then you might as well consider yourself defeated specially if you are not a Western protectorate. In Egypt which was and is a pro-Western state, the West itself helped to reverse the "revolution" and bring back the old order. In Libya and Syria the old order was not pro-Western and therefore the chaos and killing is seen as more desirable than a not pro-Western order.
Yemen- is an extremely poor country. But poverty can be misleading. Yemen is one of the two oldest original Arab states (the other being Oman) and was not colonized in the sense, lands which nowadays call themselves Saudi Arabia or UAE were. But since the WWII, with the rise of American colonies in the region in the shape of Saudi Arabia, Kuwait or later on UAE, the Yemen was pushed to become a nation in servitude to Saudis by propping up a corrupt government in Yemen that used to sign international agreements handing over Yemeni territory to Saudis. This changed with the revolution in which the Yemenis sought to oust the Saudi interference from their internal matters. The Yemeni people brought down the government in a bloodless revolution and took over the country. Saudis then went in bombarding Yemenis destroying the country and killing people in wedding parties to teach Yemenis that they can not have sovereignty since they are poor.
Syria- The situation is exactly like Libya. But with the difference that Syria has ten times the population of Libya, and Assad did not lose the rhetoric by having sucked up to West like Qaddafi did. Furthermore Assad had kept strong strategic alliances with Iran, Russia and China unlike Qaddafi who had shifted his alliances away from Russia and China to Europe and specially Italy and UK, the two countries who would later on bomb Libya with a zeal not seen since WWII.
Assad also had one more advantage to Qaddafi and this was the presence of a significant minorities in the shape of Christians, Alavis, Alawites, Shias, and Druze etc who knew if a Taliban or Isis type government ever emerges or if their territories are taken by these kind of zombies under any name for any purpose like democracy and women rights, their males will all be killed and their women will be become sexx-sllavess.
So these communities have no other option but to stand with Assad or leave the country. The zombies are highly infectious and highly dangerous. Only headshots work and coming in contact with them will mean death for the male of human species and severe birth pains for the females as they will be used to breed more zombies. Therefore the fight against the cannibal zombies is still ongoing since stopping to fight the cannibal zombies will mean only a tragic disaster of gigantic proportions and certainly not implementation of democracy or human rights. When confronting cannibal zombies, concepts such as democracy or human rights go out of the window.
