Not true. The VM is very important. The consistent & unified memory model is why Java can do synchronising, threading, garbage collection efficiently, cross platform and consistently.

As can many other languages. However, when I use .NET, I find myself wishing for maven and all the libraries immediately available. Without the VM, there would be no point in having the source. However, even with a great VM, other languages fall short of Java, IMHO. YMMV.

There are also areas where the Java VM totally sucks, frankly. How is it that we only have decent IO after more than 10 years? Sun and now Oracle hold the Java community hostage with the VM and runtime. Time to move on.
