I'm kinda starting to agree with Bubba.
Based on the conversation Cap had with Logan it makes him seem like he doesn't have any real plan at all, he just wants to be in charge of the problem.
Captain America's whole plan, as detailed in New Avengers #25 is to MOVE THE BAIT OFF PLANET. That's all. He doesn't want Hope killed but beyond that he has no real way of stopping the Phoenix from taking Hope over. While the Space Avengers are attempting to stop the Phoenix before it reaches Earth, neither Steve or Tony gave that plan much of a chance.
So, yeah, Cap is right to want to protect Earth from the Phoenix (because they have no idea what's going to happen when it arrives) but is talking a big game without much of a plan.
This issue was damn good. I enjoyed the hell out of it.
