Poor “negotiating tactic” tactic

From the Guardian:

The Brexit secretary is determined not to table a figure for the price the government is willing to pay to settle Britain’s obligations as it leaves the EU – believing that putting a figure on it would be a poor negotiating tactic.

Might I suggest that presenting as sole justification for your uncooperative negotiating tactics their quality as “negotiating tactics” is itself a poor negotiating tactic?

Not everyone shares the British view that everything in life is a sporting competition.
