Why French naval investment stalled

Why did France not invest more in naval infrastructure between the wars?

Constraints existed, but unstable politics and indecision over spending were the decisive practical obstacles.

A plausible strategic explanation differs from the political reality of the French case. Limited money and manpower could justify selective investment rather than an unlimited fleet programme. French governments did not consistently adopt and execute that strategy, however. Repeated changes of government and unresolved arguments over spending prevented a coherent infrastructure programme from being carried through.
