I agree that Alexandra would probably have fared better as an English Queen; she certainly wouldn't have been murdered, that's for sure.
I think it would have been easier for her because she wouldn't have had SUCH a prominent role, seeing as our monarchy is constitutional, and she wouldn't have felt such pressure to have a son, etc. Plus, of course, no Orthodox religion here, so her intensely spiritualist side wouldn't have had a chance to come out, and so no Rasputin.
I agree with Grace; Alexandra was simply not suited to a public role at all, but she was going to have to have some sort of public role, whoever she married, seeing as she was royalty. Russia was probably the worst country she could have married into for her temperament, and if she had married the heir to the British throne, I think her life would have been a lot more comfortable and less stressful for her.
She may though have suffered from the anti German feelings during the war, though I doubt to the extent she did in Russia.
