We know by now that some ardent left wingers here support and recognise Marxist Corbyn as being the second coming, and he, along with all powerful hard left Momentum in the background. will cure all the world's ills and wipe out poverty and suffering in one fell swoop.
He'll also ban the making of arms and the UK's defence budget will no longer exist, because any war-mongering/terrorist enemies will come to their senses when he calls them 'friends'. He'll understand though the radicals and religious fundamentalists in our midst who have points to make....they'll talk about home made bombs over tea.
Using the arms trade as an excuse for Corbyn's nasty anti Israel stance, and terrorist supporting gaffes as a stick to beat ANY government is pretty desperate trisher.
Or will there not be an army, navy and air force or an arms trade, weaponry, and military forces when socialists are in charge of the country??? 
Just asking. I think every PM in my lifetime has had to accept that the industry surrounding weapons exists and the makers of arms also supply them because - well, there would be no point making them otherwise.
In an ideal world there'd be no need, but we know Corbyn and co are not likely to create any sort of socialist/Marxist heaven on earth if other hellish socialist regimes are anything to go by.
