I agree with with you, i did say we need a faster delivery system, and it seems a better idea to make them miss rather than try to completely
annihilate them considering you run the risk of fragmenting them. Even better if we could stear them into the Sun, that way they will not hit anything
How are you suggesting we change there trajectory once there?

Depends how massive it is and how close it is when you get to it.
If its small enough/far enough you could gravity tractor an object by simply maintaining station close to it. The object and the spacecraft will exert
pull on one another. If you use propulsion to maintain a fixed distance you will slowly pull on the object. Thats a pretty elegant solution but its
dependent on a lot of things. The farther away you meet the asteroid the smaller the amount of motion you need to give it to trigger a miss.
The other solutions all require interacting with the body directly and i've heard a number of ideas, from attaching electric thrusters to excavating
mass from it and throwing it off into space at high velocity.
We need a tool kit since not every option will work best for all asteroids.
Bigger bombs are some way down the list of tech we need to solve this problem. Although its historically always been easier to get money for bigger
bombs than science, utility be damned.
