The world is biased. The west (Europe, US, Canada, Israel) don't even consider African and Middle Eastern people as lives. They don't count. They are not reported. Rest of Asian and South American's are somewhere in middle, not human enough but worthy of mentioning in news.
The only fight in their radar is Ukraine and Russia, which is near Europe as Europe can feel the effect of war.

The Houthi are just trouble in their view and they believe bombing them to dust would solve the problem. The reason why they are doing everything to stop Iran from making a nuke is a nuke would be a bigger trouble.
