Bexy...Iran is clearly building a Nuke....rightly or wrongly....
however, rightly or wrongly, we have a MASSIVE vested interest in the region (obvious reason) and that interest extends to me and you (like it or not)
the UK and our allies would be utterly foolish not to look after OUR interests in the region...and indeed, not lets those who we rely on (rightly or wrongly) get utterly intimidated by a regional aggressor (again, depends how you see it)
