Brexit & Royal Assent

As most of the world is aware by now, the United Kingdom voted in June to exit from the European Union.

While the vote is guidance for Parliament, the actual act of exiting the European Union (by invoking Article 50 of the Lisbon Treaty) formally has not started by the House of Commons.

I wonder if Parliament passes a bill "activating" Article 50 by petitioning the European Council, what measures could be taken inside the UK to prevent the formal exit request?

In 1707, Queen Anne was the last British monarch to refuse royal assent to a bill of Parliament. Accordingly, the monarch has the constitutional authority to refuse royal assent (veto). By this way, could Queen Elizabeth II save her nation from potentially losing Scotland and Northern Ireland?

Hitler in Crimea

Hillary Clinton referred to Russian President Vladimir Putin's recent incursion into Crimea (which is part of Ukraine) to protect Russian minorities as being akin to Adolf Hitler's wolf-in-sheep's clothing declaration of protecting German minorities in Austria, Czechoslovakia, and Poland, during the dawn of World War II.

I don't think Hillary Clinton was calling Putin--himself--Adolf Hitler; she was simply stating that his tactics are similar. We can already see that what she said is true. The Crimean parliament has voted to secede from Ukraine and join Russia. It will put the matter before the people of Crimea in the next ten days.

Secretary Clinton also used an interesting phrase in her speech, in which she stated that President Putin did not simply want to solidify Russia, but he wants something more grand. He is looking to "re-Sovietize" the Russian frontier. Perhaps after bringing Ukraine to heel, he will work on the other former Soviet states. Who's next? Georgia? Armenia? Certainly, they contain Russian minority groups worthy of Mother Russia's very firm protection.
