Yes you said it, it really is an illusion. ITs just stuff politicains do to make all the sheep happy and think "well I reckon the goberment really do cares about us". You can call it a curtain to keep out the prying eyes on the bad deeds of selling billions of dollars of weapons to Saudi Arabia that in return they use to comment war crimes on Yemen. An illusion to cover up the fact the Trump campaign colluded with Israel. etc etc etc.
