There is only one party to blame for Yemeni children's horrific suffering: Saudi Arabia and its allies. The war has ultimately been the result of Saudi Arabia's aggression toward Yemen and the resulting siege it imposed on Houthi-controlled areas. Saudi-US aggression must bear the responsibility for this humanitarian cataclysm.
The suffering of Yemeni children falls on Iran and its proxy force that only seek to terrorize Yemenis and cause chaos in the region. Though the Houthis and their supporters pretend that Saudi Arabia and its allies intervened in Yemen out of nowhere, they only responded when the Houthis captured Sanaa and the internationally-recognized Yemeni government invited the intervention. Iran and its proxy forces must take responsibility for this atrocity.
