[Star Wars] How did nobody in the Senate or the Jedi Order question the extremely convenient timing of a massive army of clones?

Yes yes Palpatine IS the Senate and all that jazz.

It was this moment that is the beginning of the three year-long process where the Republic senate bends over and let’s Palpatine have its way with them, foisting more and more emergency powers on him to solve the crisis at hand until he can form an Empire to thunderous applause. They basically were shitting bricks at the fact most of the corporations and nearly the entire Outer Rim had **just declared war for the first time in a thousand years**, and when that cool centrist Palpatine whips out a massive clone army so they don’t need to make a draft and threaten their power, the senate goes “oh thank god we have an army” and doesn’t look further. 

As for the Jedi, they thought they had all the pieces. Jango was a bounty hunter, him taking multiple jobs for different people like jizzing in a cup for the Kaminoans before helping out Dooku isn’t that out of the ordinary. Plus they don’t learn that Dooku is Tyrannus until well into the war, so it gives them even more of a justification. 

Now it’s safe to say that they should have tried to investigate more, and reevaluated as the war went on. But Sidious had exploited their attachment and dependancy on the Republic to his advantage, knowing they would choose to break their principles and lead a slave army to protect the corrupt government rather than face the PR nightmare and massive rebuilding they’d have to do by distancing themselves and staying true. Its all how he manipulates people-giving them choices, and shaping things up so they take the easier one that really only benefits him.
