You really should reread my first comment.
As for the treaty you could read other articles in that treaty[0] while you at it:
Article 6
Each High Contracting Party shall refrain from participating in, or supporting, any actions directed against the other High Contracting Party, and shall not conclude any treaties with third countries against the other Party. Neither Party shall allow its territory to be used to the detriment of the security of the other Party.
Article 7
If a situation arises which, in the opinion of one of the High Contracting Parties, poses a threat to peace, violates the peace or affects the interests of its national security, sovereignty or territorial integrity, it may propose to the other High Contracting Party that consultations on the subject be
held without delay. The States shall exchange relevant information and, if necessary, carry out coordinated or joint measures with a view to overcoming the situation
Article 11
The High Contracting Parties shall, in their territory, take the necessary measures, including the adoption of appropriate legislative acts, to prevent and suppress any activities that constitute an incitement to violence or violence against individuals or groups of citizens, based on national, racial, ethnic or religious intolerance.
Article 12
The High Contracting Parties shall protect the ethnic, cultural, linguistic and religious diversity of ethnic minorities in their territory and shall create conditions that encourage such diversity.
Each High Contracting Party shall guarantee the right of persons belonging to ethnic minorities, individually or together with other persons belonging to ethnic minorities, freely to express, preserve and develop their ethnic, cultural, linguistic or religious diversity and promote and develop their culture without being subjected to any attempts to assimilate them against their
will.
