Arthashastra
स्व विक्षिप्त मित्र विक्षिप्तयोः स्व विक्षिप्तं स्व भूमौ विक्षिप्तं सैन्यम् आपदि शक्यम् आवाहयितुम्, न मित्र विक्षिप्तं विप्रकृष्ट देश कालत्वात् ॥
Of armies kept in one's own country or under the protection of an ally, that which is kept in one's own country can possibly be disbanded in time of danger, but not the army under the protection of an ally, as it is far removed in place and time.
english translation
sva vikSipta mitra vikSiptayoH sva vikSiptaM sva bhUmau vikSiptaM sainyam Apadi zakyam AvAhayitum, na mitra vikSiptaM viprakRSTa deza kAlatvAt ॥
