Sure, this can be a bit controversial, but if you feel differently, make a list of ways that C++ is better than D (and there are reasons).  D has hundreds of incremental improvements to C++, but this list highlights some of the biggest.

About D (From digitalmars.com/d):

D is a systems programming language. Its focus is on combining the power and high performance of C and C++ with the programmer productivity of modern languages like Ruby and Python. Special attention is given to the needs of quality assurance, documentation, management, portability and reliability.  The D language is statically typed and compiles directly to machine code. It's multiparadigm, supporting many programming styles: imperative, object oriented, and metaprogramming. It's a member of the C syntax family, and its appearance is very similar to that of C++.
