It turns out, London Mayor Sadiq Khan was right: Terror has become part of everyday life in London.

The Muslim mayor made waves last year when he shrugged off terror attacks as just another annoyance of big city life, seemingly no different than traffic jams or busy sidewalks.

Khan's remarks came after a terrorist ran down London residents and tourists on the Westminster Bridge near Parliament, killing four people and injuring dozens more. He said that terror attacks in London were "part and parcel of living in a big city," which set off a firestorm of criticism that the mayor was not taking terror threats seriously.

It wasn't the only time Khan stuck his foot in his mouth.

In May 2016, Khan also condemned then-candidate Donald Trump's proposed travel ban saying it was "ignorant" and that "London has proved him wrong" in its inclusive approach to counter-terrorism.

But has London proved President Trump wrong?

If anything, Europe has become the poster child of what not to do regarding national security.

The open-borders policies enjoyed by 26 countries within the EU has been an open invitation to commit atrocities on European soil. Europe has suffered from its most brutal terror attacks since the onset of the migrant crisis in Europe beginning in 2015. A stunning 1.5 million refugees have flowed into the EU from countries such as war-torn Syria and other places that harbor extreme violence and have virtually no records to background check the refugees. This has been a recipe for disaster.

The migrant crisis was blamed for the terror attacks in Brussels in spring 2016 which left 32 dead and 300 people injured.

At least one of the attackers in the November 2015 terror attacks on the Bataclan concert hall and other venues around Paris was carrying a passport belonging to a 25-year-old Syrian named Ahmad al-Mohammad. The mastermind of the attack was a Belgian-Moroccan jihadist operating in Syria.

The crisis has also been credited for a wave of violent sexual assaults such as rape, including an outburst of migrants assaulting 1,200 women on New Year's Eve 2015 in Cologne, Germany.

In the summer of 2016 in Nice, France, a Tunisian citizen taking up residence in France drove a truck through a Bastille Day celebration killing 86 people and injuring 458. The Islamic State took credit.

Now, terrorists have planted a bomb on a busy subway in London injuring at least 22 commuters, proving that terror attacks have indeed become a routine threat to everyday life there.

The one area where London's mayor gets it wrong?

After the atrocious attacks in Paris, London, Brussels, Barcelona and beyond, Europe has a long way to go before it can dole out advice to America on how to keep her citizens safe.
