No. In Call of Duty: World at War (Wii), the Wii Remote (Pointer) controls aiming/shooting exclusively.
Control Scheme:
The gun viewmodel is locked to the IR Pointer coordinates. The Nunchuk analog stick moves the Character Body, not the crosshair.
Comparison: Metroid Prime 3 / Conduit allow "Free Look" decoupling (Nunchuk moves screen center). CoD: WaW does not support this. It uses "Pointer = Aim" exclusively.
Tip: Adjust Pointer Sensitivity and Dead Zone in Options $\to$ Wii Remote Settings for better control. Use Wii Zapper shell for stability.
