Not only mission creep, but putting men on the ground to enable strategic strikes in the first place is a tactical and logistical nightmare, of course they could just go for the Shock and Awe BS, but that would negate the "We are only stopping the Nuclear program" defence.
The only real way to deal with this is by negotiation.
