It’s a war, so there is suffering. As with every war ever, it’s not ‘bad’ just because it’s led by Arab powers. They are doing their best to keep extremism away from the peninsula without relying on British and US armies coming. Donating money to some organisations, including some linked here, can go on to fund a group that you might not like. There are three factions at war: the Saudi led coalition, the Houthis, and ISIS led groups.
The GCC led coalition (KSA, UAE) use American owned mercenaries to fight their wars. This is problematic as there is sometimes a deliberate lack of communication from these groups to leadership. There have been some human rights issues involving interrogation, but primarily - they have simply fought what is a difficult and brutal war given the demographics and geography of Yemen.
The Houthis use a lot of child soldiers (just under a half of their forces are children), and plant a lot of land mines. They also use the Hamas tactic; they hide their weapons, offices and personnel in civilian areas, in the knowledge that the Saudis will either not bomb - or they will bomb and face backlash in the media. They take doctors hostage, and hijack aid shipments. Saudi now work with the Red Crescent to guard food aid to get it to people in need, so that may be a good place for donations. They run protection rackets on businesses, and there is a lot of violence. They are backed by Iran, Hezbollah and have even received weapons from North Korea.
ISIS? Well, I’m sure you have a clue what it’s like to live under ISIS control. The restrictions on women, the sex slavery, the lack of education, the sheer violence.
I urge you all to look into this carefully. It’s a lot more complex than is often painted by NGOs. Be careful with where you donate, lest your money goes to an aid shipment that is hijacked along with the aid workers for ransom from the Saudi led coalition. They aren’t legally allowed to pay up. If they did, that money would go to Iran and Hezbollah and North Korea for weapons to continue a war that needs to end. If they don’t pay, those people die and the aid is never distributed.
In a war of attrition, when one party is on its last legs, sending aid can simply extend suffering.
