Peace,

While being aware of the fanciful notion held dear by the cosy left, and the anti-war brigade, that Saddam, that loyal and close friend of the West, was armed to the teeth by the US and UK, the reality is somewhat different.

You ask the question:

"It was not clear what support countries like Estonia, Latvia, Lithuania, and Bulgaria were providing to the US coalition."

The answer is rather obvious and also applies to the type of support that the other former Warsaw pact and Soviet Satellites could provide. Counter to popular belief, NATO does not possess CW or BW Weapons, Soviet Russia and the Warsaw Pact countries did, probably still do.

Now you are about to go up against an enemy that you,the rest of the world and the rest of the world's dog, believes has CW and BW weapons, I would say that it would be a pretty big plus to have people who were trained from the same manuals, on the same equipment and on the same procedures as your enemy. Who better to advise on condition and safety of stored munitions - rational? logical? reasonable?
