Not sure Britain invaded the Falklands. They went to expel the invading Argentinians.

No - they are not invasions

The troubles were a period of terrorism in Northern Ireland
The Malvinas is the Argentinian name for the Falkland Islands which Argentina did actually invade
The Raj is the name for the British Empires rule over India
The Crusades are a complicated series of military actions primarily aimed at recovering territory from Muslim invasion

So two could use the word invasion - two most definitely could not

Because the Raj is included you can’t even describe them as conflicts

Read a history book

What`s wrong with just `wars`? Invasions are wars.

No

British invasions? I think not. Disgraceful description. Or ignorant.
