Which brings to mind something I didn't like about the episode. Namely, Archer shooting off his mouth and risking an insterstellar war. Doesn't the Klingon Empire have a military vastly larger than Starfleet at this point {even granting roughly equal technology, wouldn't the Klingons arm every single space vehicle they made? Including lifeboats, which they probably wouldn't make in the first place?}.
When the one Klingon threatens to park a battle fleet in Earth orbit, shoudn't Archer have had more of a reaction to this? We understand that in later Trek Starfleet can offer some real deterence in the face of Klingon bluster. But that's not the case in Enterprise...
