Do you know what was the single moment when Britain could have prevented the bombing of London?
At Munich, 30th September 1938.
The day when UK, France and Italy decided, that the best way to avoid war in Europe is to hand over a big part of Czechoslovakia to Germany.
Czechs were well equipped, with fortifications on borders and ready to fight if there was a chance for support. Actually, Czechoslovakia was part of military alliance with (some of) those western countries, as Czechoslovakia had a significant army and industry, including military industry in that times. But the west told CZ to surrender.
Betrayed Czechs did, at least officially.
(Skipping here Hitler's attack on Poland after that, it's already long)
What was the surprise when Hitler came to France and UK. Equipped with both German and Czech weapons, with German military factories running nonstop using Czech people as a slave labour
Current Russia isn't a democracy. Current Russia doesn't respect the UK, despise your lifestyle.
If you find a peace, how long will Russia keep it? It has been only 8 years since the settlement after Russia attacked Ukraine and took Crimea.
Ukrainian grain is very important for big part of the world. If Russia gets control over it, it can starve big part of the world (and in past they did intentionally caused famine and killed millions of people), cause incredible migration crisis and get overall food prices through the sky.
It is good enough reason to support Ukraine now.
Ukraine is willing to fight - for their country and their freedom. Their fight is shaping your own future and safety. It is weakening Russia a lot. All it takes from the UK now is some level of material/monetary support, some military intelligence, some equipment.
If you can't afford the support now, do you think you afford the consequences?
