They did recover mobile labs in Iraq. Saddam himself was interested and pursued black market nuclear technology from the same three nations that are arming Iran, e.g., Italy, France & Germany. Each of these three countries do an end around the sanctions and the governments & corporations are corrupt with kickbacks from Iran.
There was a three week pause when a series of Russian convoys went into Iraq from Syria hauling out a lot stuff, including aircraft and vehicles which were buried in the deserts in Syria just before the US put boots on the ground. There was a cover up.
They did not recover that which Colin Powell said they had and supposedky had extensive numbers of which Trump talked about.
They did not have an extensive nuke program nor were close to having a nuke as claimed by Netanyahu.
Where were Bush, Powell, Cheney, Netanyahu at - day and night - on tv showing pictures of the convoy and cover up? Or OTOH Why would they all argue for interventionism and then be involved in a cover up if they were? And where is the evidence of all of this going into Russia?
