“...some of us would say war drags on and has a habit of drawing you in.”
Men do the hard things, not because they want to, but because they must. The cost is the cost.
If the hard thing, stopping Hitler early, had been done at the first or second warning probably sixty million people would not have died the way they did. But the can was kicked down the road until it exploded.
But you and Israel have done away with most of their leadership. What’s left is an even more hardened, collective IRGC.
The enemy can prove to be resilient even in the face of ground invasion and total war. Look at Vietnam and Iraq for evidence.
Unless you favor this approach and are prepared to spend 20 years on it in the case of Iraq. It’s totally pointless in my view
