You are basically making stuff up as you go along.
Ironically, this is me and the then UK Defence Minister versus a couple of guys on the internet.They are living on twitter.
'We will be watching as part of our steadfast commitment to keep Britain safe,' says Defence Secretary Michael Fallon
That the act had political significance is without question, by anyone with any kind of substantial interest in the matter.It's clearly designed […] to test our response, and any weaknesses in the alliance, and we must make sure we respond in due measure.
I'm not sure what point you are trying to make, when the broad shape of the issue is clear to anyone balanced.Yes, do you think they use fresh water to flush toilets and for fire systems? Do you think these systems only pump in water when a toilet is flushed?
The QE2 pumps in seawater under pressure, which it processes for its freshwater need. I'm sure that, at any given moment, this means there is an amount of seawater on board in the process.
If you ask the question "how did a load of seawater flood a couple of compartments?" the answer seem to be that it didn't come in because of a fault in the hull, but because one of the pipes sucking in seawater for processing catastrophically failed.
"Internal system" doesn't mean internal water. It means an "internal" system that sucks in external water failed, allowing that external water into the boat.
A balanced person wouldn't need the detail of explanation that I'm giving. But there it is for you.
