the problem is that if we get the nod to buy the 22's then israel will want em and then pakistan will want a squadron or 2 then south korea and before you know it nz will want one or maybe 2 plus a trainer to keep up with the mates across the pond (or in kiwi , the 'dutch' ).
the yanks will have trouble breathing if that happens but maybe we could play hardball with the yanks and tell em we will buy the latest vodka powered aircraft if they don't paint a few 22's with roo's on em,
