Oh really?
What is your proof about our support for Yemeni army?
BTW even if we have supported them , it is not yet happened , in fact we have supported oppressed Muslims against mass murderers and thugs of UAE/KSA. Although due to land/sea blockade on Yemen, no one can supply them except for their own industries that had old China-Soviet made missiles. Scuds specifically and Chinese C-801 anti ship missiles.
Again, even if we were supplying them, you cannot make it an excuse for your mass murder in Yemen and don't forget your meddling in Syria and Iraq. You supplied rebels and terrorists, however Al-Qaeda in Yemen still owes it's strength to your coalition.
