Yoda is shown beginning to tune into the Qui-Gon Force frequency in ATOC (or is it the other way around?)

Qui-Gon does find and put his foot down about Anakin (and we all know how he turned out).

So while it doesn't completely fix the problem (only a trip in the TARDIS armed with a cricket bat could do that) it does ease the problem a bit if the Jedi ability to sense what the dark side is up to is clouded and they assume that one of their own made the necessary preparations.

They are stuck in a difficult place.

The Senate have rushed through a motion legitimising the creation of an army that already exists to counter a threat that already exists.

In a sense the clones are outside their control anyway.

It would be also help the situation if somehow a call for continued investigation and assessment of the army was made. Yoda seems to be the most sceptical while Mace and Obi-wan seem to see the army as a gift from the Force (they should have checked out the horse shaped parcel before pulling it into the city first however, such are the many perils of the postal system).
