Learn English – What does “got it in” mean in this context

It seems to be saying that they want to see some action, but that they do not want to see a military strike, as that would be going overboard and doing more harm than good.

I think that saying "but it's not necessarily a military strike, mind you" sort of misses the mark a little bit, and conveys the idea that the operation they have in mind is even more threatening than an ordinary military strike, like a nuclear missile or something.

As a replacement for "just", I think "mind you," and "but" both provide good approximations, but I don't think that "mind you" without a comma is any good, as in @dcaswell's answer

I also do not agree at ALL that the original version sounds awkward, speaking as a native Australian speaker.

A better definition of "got off easy" would be "without much hardship or cost". That can mean that you didn't get punished very severely, but in this context it means that whomever was speaking got a good deal on the Quidditch World Cup tickets they bought.

The phrase "got off easy" has the connotation that the usual consequence or cost is much more unpleasant or costly than the actual consequence/price in this situation. The tickets could have cost a lot more, but he "got off easy" with a lower price.

Some examples:

She might have gone to jail for a long time, but got off easy with just community service.

I could have ended up in the hospital, but because I was driving slowly I got off easy with just bumps and bruises.

I didn’t know it at the time, but apparently, I got off easy. When my best friend from college got married last summer, I had to spend only $1,000 total for her bachelorette party in Las Vegas, my plane ticket from New York to Los Angeles, hotel room, bridesmaid’s dress, shoes, hair styling and wedding gift.
