Why does Germany still not have veto power in the UN, considering they are one of the world's leading economies?

The UN security council permanent members are composed of the major allies involved in WWII victory, i.e. the United States of America, the Soviet Union (replaced by the Russian Federation), the Republic of China (replaced by the People's Republic of China), France, and the United Kingdom. As Germany was part of the Axis, they did not have a UN security council permanent seat when the UN was formed, and there are no provisions in the United Nations Charter for changing the UN's structure.

And while it could make sense to give Germany a permanent seat, it would face much opposition as well:

• Germanophobia is in full swing in Europe even today as people from the PIGS (Portugal, Ireland, Greece, Spain) resent Germany's strong role in preserving the European Union. One wonders just how much it will be widespread if Germany assumes a bigger international presence.
• Germans themselves may not actually want a bigger international presence.

It also opens a pandora's box of which other countries should have a permanent seat.

• India did not exist as a country at the time of the UN's founding, and should have a seat for all kinds of reasons (economic, demographic, geographic)
• There is no African country with a permanent seat.
• There is no Latin American country with a permanent seat.
• Should France and the UK still have a permanent seat, as there are already 3 European countries with a permanent seat?
• There is no Muslim country with a permanent seat, should there be one? Turkey and Iran are likely the best candidate on paper, but are unlikely to ever be accepted by the World or by Muslims themselves. Indonesia could also be a good candidate on paper but it might also not be accepted.

I would personally support a German permanent membership of the UN security council, but getting this done is fraught with problems.
