Arab illegals make a riots to avoid registration

These illegals would want to go further from Hungary, to Germany, England and Sweden, but first they must be recorded in Hungary, which they refuse, because if they do so, later the Western countries can deport them back to Hungary. So these riots started when Arab illegals tried to runaway from this registration camp.
During the riots illegals have been fighting between them also. Few hundreds of them managed to escape but were later caught and sent back. Libtard media tried to abuse this event to attack the Hungarian police for alleged mistreating of these Arabs. They presented this camp as a German WWII concentration camp, and this is simple ordinary registration camp. They are worse than Goebbels.
It should be noted that this illegal migrants are almost totally Muslims, most of them do not have any documents, they came mostly from Syria, Iraq, and Afghanistan, the vast majority (80% of them) are men of military age between 20-30 years.
So the first question is, why all this military age men in the best years of their life did not took the guns to fight for their country, since they claim that they flee from the war, and also why they just fled and left most of their women, children and the elderly behind in the country of origin, remember it's where the war is as they claim? And the second question is why they do not flee to the culturally closer rich Arab countries: Saudi Arabia, Qatar, Kuwait, United Arab Emirates, Bahrain?
