Football : What Happened?

OK, so here's the deal. Germany is in the semi-finals but both Brazil and England are out?
Plus I thought Korea got into the semi last word cup but this time they didn't even make it into the best 16?
What the hell happened?
I'm a Germany supporter (From previous post: cause of their pretty jersey.) so of course I'm happy that the got in but Argentina got kicked out too! Now there are only European countries left: France, Portugal, German and Italy. This is the first World Cup I'm watching so I'm not sure but I didn't even know Italy was any good. I thought they were predicting that Brazil will make it to the finals and the comentators were going like "All Brazil fans have already marked out 10th of July on their calenders." because they were all so sure Brazil will make it through or something.
Plus, I totally hate Portugal! I mean Figo sucks and Christiano Ronaldo is just plain stuck up! Well, at least I think he is. And during the match, Rooney shouldn't have been given a red card because the step was obviously an accident and the little push at C. Ronaldo was clearly just a one time thing.
When Beckham got changed off the field I really felt bad for him because it must have been hard for him to miss out on such a hard match. Gosh, that England vs. Portugal match had me shouting and screaming with dismay in front of the TV the whole night.
As for the Brazil match, I totaly missed it but I saw the replay and my god, Zidane is good! As for Brazil, I guess it just wasn't their day because they were making quite a few silly mistakes that they obviously couldn't afford at such a stage. Or was it France's superb defending skill? I don't know, not really a football expert.
As for the Germany vs. Argentina match, a lot of people were saying Argentina would win but of course I sruck by my pretty jerseys and was totally supporting the home team and when Argentina scored the opening goal, I was devastated. And the score stayed the same for quite some time and I was getting a bit worried and worse of all, since I was in Genting I couldn't watch the match so I had to rely on Mae's info only and it was so nerve-wracking!
But then the stars shone on the Germans and they were able to draw after the extended time. When it came to the penalties I was pretty sure the Germans would win because their goalie is really good plus they did all the research on the Args so they knew where the opponents tend to shoot. So yeah, I say the Germans won fair and square.
