I disagree. The DEAD (destruction enemy air defences) phase has become a custom, it was no necessity. Most of those air defence missiles are 1960's vintage, they could probably not even kill civilian aircraft any more.
If someone had challenged me to fly in a Learjet over those air defences in a 1 € : 1 million € bet, I would have accepted. To survive the landing would have been the biggest challenge to me.
