your so called hyperspace communication is not that dependable ou in the outer rim. And all this happened quickly. The whole war was done in 5 years. I don't think any facts came in about Sperindal until Leia mentions it. If they had concrete info from hyperpace com, then they would have known Leia was telling the truth. i still think politics played a big part in this, and i do think the core worlds are rather insulated from the rest of the galaxy. It all made plausible sense to me. But it was the force philosophies on display really for the first time with Anakin and Jacen that i thought was fascinating over all, and i loved the depth of the vong tech. There was a lot great about this series, even if you don't think it is 100% realistic. It is sci fi. Yes there needs to be some realistic qualities even in sci fi, but i think it was realistic enough. this just showed how blind and stubborn the senate really was.
