This is intellectually bankrupt... But I will anyways help you reason.. UAE has never made any threat towards Algeria... It can impose sanctions via blockade of trade between UAE and Algeria but I doubt the article is based on reality but rather another assumption news which is fake news. You are talking about Israel constantly but they are viewed as irrelevant in the larger picture geo-politics context in these countries because it is just a tiny country that doesn't pose threat but just an outpost.
Nobody can undo UAE, Saudi Arabia or the GCC, Jordan, Eygpt and co militarily.. Only NATO which is a huge coalition.. The GCC military wing called ''Peninsula shield'' Has around like 913 fighter jets that is 3rd most fighter jets in the world after only US and China... There population is 65mio but the Peninsula is more armed than china on per capita and by far..
On a regional level no entity can defeat Peninsula shield not even Turkey that has the most advanced defense industry.. There are 5 more defacto members of the peninsula shield these are Jordan, Egypt, Sudan, Tunisa and Morocco... Jordan, Sudan and Egypt are directly linked to the Peninsula shield will have access to any conflict due to geography.. they number together anywhere upwards 500m NATO is the only one that has the necessary manpower and logisical hardware quanitity.. Algeria is heavily armed herself but will not hold out against them Even if Tunisa and Morocco were to launch double attack on Algeria it could find herself in a very tough existential fight which is unpredictable and nobody knows the outcome...
Because Morocco has been well armed relatively close to Algeria even tho I think Algeria is better armed overall Morcco is slightly behind Algeria not by much tho. So Morocco is technically not a walk in the park plus they have the population numbers to make this a dog-fight and the atlas mountains and their conventional ground forces is strong they are the 10th country with most tanks plus their airforce and air defense systems is good but all in all strong armed overall..
Anything on paper can sound good. In reality this coalition cannot defeat the yeminis and as we talk now part of egypt is still occupied by isis. Similar things were said when arab nations went to war against tiny isreal.
