καὶ ἀποστᾶσα—‘when revolt has actually taken place.’
τὴν δαπάνην ἀποδοῦναι καὶ τὸ λοιπὸν ὑποτελεῖν—here, naturally, the least is made of the terms dealt out by Athens to revolted allies who submitted. Independent allies, when reduced after revolting, had also to pull down their walls and to hand over their ships to Athens. In I. 98 Thuc. gives a summary of the treatment dealt out to them much less favourable to Athens. By ὑποτελεῖν is meant φόρου ὑποτελεῖς εἶναι.
τίνα οἴεσθε ἥντινα—see on c. 39, 7.
παρατενεῖσθαι—‘be strained to the utmost extremity.’
τὸ αὐτὸ δύναται—cf. I. 141 τὴν αὐτὴν δούλωσιν δύναται.
