Can a program see the draw from this position?

I can see the following white king,black rook table.

white king:d6,e6,f6,g6,h6 black rook c6
white king:d5,e5,f5,g5,h5 black rook c5
white king:d4,e4,f4,g4,h4 black rook c4
white king:d3,e3,f3,g3,h3 black rook c3
white king:d2,e2,f2,g2,h2 black rook c2
white king:d1,e1,f1,g1,h1 black rook c1

white king d7,d8 black rook d6
white king e7,e8 black rook e6
white king f7,f8 black rook f6
white king g7,g8 black rook g6
white king h7,h8 black rook h6

white king c8 black rook d8

Unfortunately programs are weak at simple tactics so they cannot see it and
evaluate the position as big advantage for white.
