Syrian Dictator Shadows Noose

beware a Syrian Dictator who cornered warns
threatens to use mass chemical weapons
not on his own citizens but foreign invaders

chemical weapons is a card previously badly used
chemical Ali father dictator Saddam this card abused
slaughter own citizens is post war crimes reviewed

hangman's noose is time tried tradition for crimes
humanity inflicts on loser nation toppled leaders
super power immunity veto not among loser options
