Along the Jordan river the Israeli army built a chain of strongholds and fortifications. Since 1994, after the peace treaty between the countries was signed, they were abandoned. Today they got a new use and became a home for bats. Eran Levin, his team and the soldiers of the Jordan valley regional regiment prepared the bunkers to make them more suitable for bats. Eran Levin wrote this article about his work. There is also a PDF about his work (see pages 7 - 10).
Like the bible already says in Isaiah 2:4
וְשָׁפַט בֵּין הַגּוֹיִם, וְהוֹכִיחַ לְעַמִּים רַבִּים; וְכִתְּתוּ חַרְבוֹתָם לְאִתִּים, וַחֲנִיתוֹתֵיהֶם לְמַזְמֵרוֹת לֹא יִשָּׂא גוֹי אֶל-גּוֹי חֶרֶב, וְלֹא יִלְמְדוּ עוֹד מִלְחָמָה
And he shall judge among the nations, and shall rebuke many people: and they shall beat their swords into plowshares, and their spears into pruninghooks: nation shall not lift up sword against nation, neither shall they learn war any more.
فَيَقْضِي بَيْنَ الأُمَمِ وَيَحْكُمُ بَيْنَ الشُّعُوبِ الْكَثِيرَةِ، فَيَطْبَعُونَ سُيُوفَهُمْ مَحَارِيثَ وَرِمَاحَهُمْ مَنَاجِلَ، وَلاَ تَرْفَعُ أُمَّةٌ عَلَى أُمَّةٍ سَيْفاً، وَلاَ
يَتَدَرَّبُونَ عَلَى الْحَرْبِ فِيمَا بَعْدُ
