I have not been paying any attention to what was happening in Yemen, but after looking at the Wikipedia page on the subject it looks like the bad guys are the same extremist Muslims who have been the criminals in Iraq, and in Afghanistan, and in Syria, it is the same bunch of bad extremist Muslims.
https://en.wikipedia.org/wiki/Saudi_Arabian-led_intervention_in_YemenSaudi Arabia, and Egypt, and all of the Arab nations have been supporting Hadi against the extremist Muslims, it is the moderate Muslims versus the extremist Muslims.
And the UK, and the USA, and Russia, are selling weapons to the Saudis, etc.
Meanwhile, children are starving.
UNICEF is working on everyday necessities such as clean water and food for the children.
https://www.unicef.org/yemen/The answer of course is to have freedom of religion, and separation of church and state, and for the government to represent all citizens regardless of religion, etc. And for the good people to unite to stop the terrorists. It is easy to put in peace and rule of law once they decide to do it, and unite in the act of making peace happen. You cannot force your religion on someone else, and the government of Yemen must represent all people of their nation regardless of which religion a person belongs to, they need to respect a Jew the same as they do a Muslim. They need to realize that all men are created equal regardless of race or religion, etc. They need to unite and make peace and work together with UNICEF to provide clean water and food for the children, etc.
As UNICEF feeds the children, the children also have classes and teachers, and they can teach the children peace, they can teach the children not to hate. They can teach them to have tolerance of others, etc.
And as the adults are fed, and given aid, and as they rebuild, teachers need to go in and teach the adults the ways of peace. Education and job training is also very important for the adults. The adults will be blessed if they can find peaceful employment that they enjoy and if they can work to peacefully support their families. Even a little thing like a McDonald's fast food restaurant as a peaceful family business. Or a movie theatre as a peaceful family business. They need to learn the ways of peace.
The United Nations can provide security to make peace in Yemen while they build a Democratic government, and begin to build their nation peacefully. Saudi Arabia is biased because they are the home to Mecca, and the Saudis will not even allow a Christian church to be built in Saudi Arabia, the Saudis can help in Yemen, but it must be as a part of a team led by the United Nations, and with Christian and Jewish partners helping to make peace and rebuild.
Salute,
