The main fight is between forces loyal to the beleaguered President, Abdrabbuh Mansour Hadi, and those allied to Zaidi Shia rebels known as Houthis, who forced Mr Hadi to flee the capital Sanaa in February. But still the goverment of Yemen has not yet fallen.

That's like saying the Syrian Arab Republic has not fell. Also, Arabia, Jordan and a few others are in Yemen intervening.

well Juq the Syrian Republic of al assad did not fell yet.
Some example of fallen government/states: afghanistan under the taliban who controlled the country before the US intervention, Iran: the Shah monarchy was overthrown by the Islamic republic, Tunisia: the dictatorial government of Ben ALi defeated by the Jasmin revolution.
Yemen nor Syria have known that yet, even if they control only half of the country, their governments have not fallen.

The Houthis in Yemen are a military threat to the Kingdom of Saudi Arabia, as they proved in the 2010 invasion of Najran/Jazan by Houthi militia.
The Kingdom cannot sit idle whilst a continuous threat sits on the border, as the US won't sit idle if Canada starts threatening to take Washington DC over (not that the US would win a war with Canada btw).

Ok, Angry Panda, your "fall" meaning is different than mine.

Also America would crush Canada.

But would it?

Think about what Canada has tied to it from having the Queen... technically, the British would have to defend Canada as having the same head of state, and the same would apply to Australia, New Zealand, all the Caribbean territories that share the Queen, and then all allies in the region including Chile and all the rest.

British is a minor power Colonel against AMerica...

You got a modern example: the Suez crisis, when the English and the French representing Old Europe had a military/diplomatic lesson from both America and USSR the superpowers of that period (50s).

That episode is over. We are now in the era of the rise of American isolationism, the growing influence of China across the world, including America's "back-yard" (central America), the growing counter-moves by Russia against EU expansionism including increased influence in Greece, Spain and Hungary and increasing hostility towards the Baltics whilst fighting a "holy war" against the far-right in Ukraine.
This is a new world, a new episode and the next star will be the Commonwealth. Trust me.

Britain is no match for America, nor the commonwealth combined. I doubt they even have more population than America.

America only has ~400 million people. Relatively average.

closer to 300 million I would say

Without going into the future, if America was to be invaded by Canada right now (with the backing of The United Kingdom, Australia, New Zealand, Jamaica, Barbados, The Bahamas, Grenada, Papua New Guinea, Solomon Islands, Tuvalu, Saint Lucia, Saint Vincent and the Grenadines, Belize, Antigua and Barbuda, Saint Kitts and Nevis - all the countries that share Queen Elizabeth II), USA would crush those 16 sovereign states combined. (Also note that Tuvalu has no military, so it is technically 15 sovereign states)

I can just hear Obama looking at this and saying "Damn right"

Also, probably half those countries wouldn't invade, they're nice Caribbean countries with more loyalty to America than Britain.

The truth is that Britain is also more or less a new colony of the USA, a Trojan horse inside Europe (that's how I see things).

Yeah, Britain's strong dissosciation feelings from the EU does make it a prey for America, but frankly, the whole EU is already a trojan horse.

no the EU is infected by a serie of virus/trojan horses: Eurobureaucrats. UK current decisions are not helping, and seriously since Thatcher things always were going worse.

Yuo think this of relevance? ... kind of?

sry Ox I know it's off-topic but I couldnt resist :D
