ANTICO,
I don't know much about this Brigade Nehamedu, except on this forum where I read the name sometimes.
Are they too stakeholders to what Eritrea is, or some kind of foreigners?
If they are stakeholders, then it is a good idea to hold on them and deal with them to negotiate with them about cooperative neighborliness on issues of mutual benefit to both sides.
Shabos attitude of mine is mine and yours is ours will not sustain itself.
