What a dilemma! only civilian Michael could get near Sollozzo to carry out the killings of Sollozzo and McCluskey

Sure thing Turnbull - Extracts:
"There's no reason for me to think he wouldn't have visited Vito if he'd been married" and “even if he were married, he'd have wanted to kill Sol and Mac--to protect Vito and for vengeance”

However...

• what about Kay? and their children?
• I can't see Kay and the kids hiding out! in the Sicilian countryside, with Michael which would be even more dangerous as well
• and the WASP! drawing even more attention
• would Michael just disappear leaving his wife and kids not knowing when he would be back?
• would Sonny be able to “square it” with Kay after Michael's AWOL same as with Mama Corleone
• I doubt Kay gonna come along with Michael in these things he has to do -- or what and more likely takes the children and moves them all to New Hampshire!
