It wont stop until get leaders with the balls to do whatever it takes to make it stop.
There is always going to be some vicious oppser with a grudge. Exactly what do you expect any leader to do about that?
Murdering a dozen people with a van does NOT change anything about our society unless we allow it to. Anyone who volunteers to live in fear like that should go to the top of TB's cull list.
It doesn't seem to happen in Eastern Europe, this is because their leaders didn't open the floodgates all and sundry like the morons in Western Europe did.
It has already changed our way of life. One example being the concrete bollards being installed on Londons bridges.
I expect this type of thing to continue and grow.
Not true where there have been many major attacks, especially bombings, in Russia, including a multiple stabbing today.
There is also a major problem where one of the world's biggest terrorists is Putin. This includes the 1999 Moscow apartment bombings which were ordered by Putin and carried out by the FSB. Putin used this to consolidate his new leadership position and launch the second Chechen war which murdering about 200,000 Chechens. The Russian invasion of Ukraine is also a terrorist attack that so far has killed 10,060 Ukrainians with the majority civilians. The Ukranian defensive operation is still called an Anti-Terrorist Operation or ATO. Russia has also stepped up its FSB wet-works with many people murdered in the West who have crossed or opposed Putin including around 10 in the UK. There current Active Measures must also be considered terrorist attacks from their massive Ddos on Estonia, to murders, bombings, hire-a-protest-mobs, hackings and shutting down their electricity grid, disrupting one of their nuclear power stations and malware issues including one when I was over there recently which took offline their flight reservation computers, banks and other important services in Ukraine. In the US he has hacked and subverted their election, regularly probes their electricity grid (which is more vulnerable than most) and their nuclear power stations.
Where Russia is rapidly going broke and Putin is having to clamp down harder and harder on Russian civil liberties, expect these Active Measures to escalate where wins against the West are a popular distraction at home which helps to prop up his regime!
