FullSimplify tries harder

FullSimplify[If[x == 0, x, 0]]

0

Hi,

When I try to Simplify[If[x==0,x,0]] Mathematica returns If[x==0,x,0] rather than 0. It seems that it does not take into account that left and right if-branches should be simplified using ($Assumptions)&&if-condition and ($Assumptions)&&!if-condition respectively. Is there a way to force that behaviour?

Best regards,
Ilya
