A bloke who's son "is in the army so I know all about this" [naval issue] rang the radio this morning and suggested that the LCUs the navy has be reflagged to Rwanda (pre-supposes that they, as a land-locked nation, have a shipping registry, of course) then deployed along the popular dinghy routes at the median and intercept them, load the contents onboard until full and then go full steam to France, drop the ramp on the nearest beach and turf the contents off, lift ramp, head back to the median, rinse and repeat. No need to go alongside, argue the toss, fill out paperwork, etc. And no-one's stepped onto UK territory - the decks would legally be Rwandan territory.
Which would work for a couple of days until the French got organised and then it would be threats, navigation-hazarding manouvres and maybe even shots over the bow. Nice idea but wouldn't fly ultimately. Not without war with France.
Mind you, that's mostly gone our way when it's happened before.
Couldn't we have Rwandan registered ships in the Channel as suggested
Migrants picked up and ask what they are trying to do
"I wish to claim asylum"
"Excellent of course you can Rwanda will be proud to have you"
Claim asylum in Rwandan territory get a free flight to their new sanctuary
