I'm not trying to be alarmist, but I honestly believe with the way things stand that if you lose your R/T and you continue towards an airfield where the approach path takes you close to a major city, especially in the US, you're at risk of being shot down. But if you try to deviate from your intended destination, eg go for your alternate, you're even more at risk of being shot down.
I think that the procedures need to be reviewed in order to cope with this changing situation. Maybe, for example, each country should nominate a designated diversion airfield to be used in the event of a radio faliure (eg Brize Norton) or if they don't already, all aircraft should be required to carry an independent battery powered communication device (eg a radio or telephone) to be used as a back up.
